A display device comprising: a window substrate having a top surface and a bottom surface; a display panel under the window substrate, an opening being defined in the display panel; a light blocking portion directly on the bottom surface of the window substrate and surrounding the opening when viewed from a plan view; a print layer directly on the bottom surface of the window substrate and at a same plane as the light blocking portion, the print layer being separated from the light blocking portion by a gap in a plan view; and an electronic component overlapping with the opening, the electronic component being in the opening, wherein the electronic component comprises a camera.
  10. 10 . The display device of claim 9 , wherein the display panel comprises: a display area configured to display an image; and a non-display area adjacent to the display area, wherein a plurality of openings is defined in the display area.
  11. 11 . The display device of claim 9 , wherein a plurality of transparent portions is defined in the light blocking portion, wherein the electronic component comprises a plurality of electronic components, and the opening comprises a plurality of openings, wherein the openings overlap with and have one-to-one correspondence with the electronic components when viewed from the plan view, and wherein the transparent portions overlap with and have one-to-one correspondence with the openings when viewed from the plan view.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS This application is a continuation of U.S. patent application Ser. No. 16/562,328, filed Sep. 5, 2019, which claims priority to and the benefit of Korean Patent Application No. 10-2018-0121157, filed Oct. 11, 2018, the entire content of both of which is incorporated herein by reference. BACKGROUND 1. Field Aspects of the present disclosure relates to a display device having an expanded display area. 2. Description of the Related Art A display device such as a smart phone or a tablet may display an image through a display area of a display panel. A bezel area (e.g., a non-display area) may exist around the display area. Signal lines for transmitting input/output signals to a screen may be located in the bezel area. The bezel area may be covered by a separate case, or the transparency of a window panel may be adjusted in such a way that the bezel area is not visible to a user. Due to the bezel area, a size (i.e., an area) of the display device may be larger than that of the display area. Various methods for reducing the bezel area in a limited size of a portable terminal have been studied to provide a larger screen to a user. SUMMARY Aspects of embodiments of the present disclosure are directed to a display device of which a display area is expanded. According to some embodiments of the inventive concept, there is provided a display device including: a window substrate having a top surface and a bottom surface; a display panel under the window substrate, an opening being defined in the display panel; a light blocking portion directly on the bottom surface of the window substrate and surrounding the opening when viewed from a plan view; and an electronic component overlapping with the opening. In some embodiments, the window substrate includes a transparent area and a non-transparent area adjacent to the transparent area, and a print layer in the non-transparent area is directly on the bottom surface of the window substrate. In some embodiments, the display panel includes: a display area configured to display an image and overlapping with the transparent area; and a non-display area adjacent to the display area and overlapping with the non-transparent area, wherein the opening is defined in the display area. In some embodiments, the display panel includes: a first display area; and a second display area protruding from the first display area in a first direction, the opening being defined in the second display area. In some embodiments, a width of the first display area in a second direction intersecting the first direction is greater than a width of the second display area in the second direction. In some embodiments, the light blocking portion has a circular ring shape. In some embodiments, a plurality of transparent portions are defined in the light blocking portion. In some embodiments, the electronic component includes a plurality of electronic components and the opening includes a plurality of openings, the openings overlap with and have one-to-one correspondence with the electronic components when viewed from a plan view, and the transparent portions overlap with and have one-to-one correspondence with the openings when viewed from a plan view. In some embodiments, the display panel includes dummy pixels in an area adjacent to the opening. In some embodiments, the dummy pixels include first dummy pixels and second dummy pixels, the first dummy pixels overlap with the light blocking portion when viewed from a plan view, and the second dummy pixels overlap with an area adjacent to the light blocking portion when viewed from a plan view. In some embodiments, the opening is defined by a side surface of the display panel, and the light blocking portion overlaps with the side surface when viewed from a plan view. In some embodiments, the electronic component is under the opening. In some embodiments, the electronic component is in the opening. According to some embodiments of the inventive concept, there is provided a display device including: a window substrate; a display panel under the window substrate and defining a first opening and a second opening adjacent to the first opening, and a light blocking portion on a bottom surface of the window substrate and surrounding the first opening and the second opening when viewed from a plan view. In some embodiments, the window substrate comprises a transparent area and a non-transparent area adjacent to the transparent area, wherein the light blocking portion is in the transparent area.
