Description

BACKGROUND 1. Field of the Disclosure The present invention relates to a display device. 2. Description of the Related Art As the information society develops, the demand for display devices for displaying images has increased and diversified. For example, display devices have been applied to various electronic devices such as smartphones, digital cameras, laptop computers, navigation devices, and smart televisions. The display device may include pixels emitting predetermined light, scan lines, data lines, and power supply lines for driving the pixels, a scan driver outputting scan signals to the scan lines, and a display driver outputting data voltages to the data lines. The display device includes a display area including the pixels to display an image and a non-display area disposed around the display area. Recently, an area of the non-display area in the display device has been minimized, but a space in which fan out lines connecting the display driver and the data lines to each other is disposed in the non-display area may be insufficient due to the minimization of the area of the non-display area. Another disadvantage of known display devices refers to display devices with a display area including a hole, whereby data lines have to be bypassed outside of the hole. A bypass line portion disposed adjacent to the hole and bypassing the hole leads to a distance between sub-pixels in the display area and the hole. Such a distance may be recognized by a user. SUMMARY The present invention provides a display device with the features of claim 1 to omit the above mentioned disadvantage that a distance between subpixels and a hole in the display area may be recognized by a user. The dependent claims describe preferred embodiments. Aspects of the present disclosure provide a display device capable of solving an insufficiency of a space in which fan-out lines are disposed due to a decrease in an area of a non-display area. However, aspects of the present disclosure are not restricted to those set forth herein. The above and other aspects of the present disclosure will become more apparent to one of ordinary skill in the art to which the present disclosure pertains by referencing the detailed description of the present disclosure given below. According to an embodiment of the present invention, a display device includes a display area including a hole and sub-pixels displaying an image, a plurality of first data lines disposed on one side of the hole in the display area and extending in a second direction crossing a first direction, a plurality of second data lines disposed on the other side of the hole in the display area and extending in the second direction, and a plurality of bypass lines bypassing the hole in the display area and connecting the first data lines and the second data lines, respectively. Each of the plurality of bypass lines includes a first sub-bypass line extending in the first direction and connected to any one of the plurality of first data lines, a second sub-bypass line extending in the second direction and connected to the first sub-bypass line, and a third sub-bypass line extending in the first direction and connecting the second sub-bypass line and any one of the plurality of second data lines. Preferably, some of the sub-pixels are disposed between each of the plurality of bypass lines and the hole. At least a section of at least one of the plurality of bypass lines, a section of several of the plurality of bypass lines or a section of each of the plurality of bypass lines may be disposed in a non-display area which is at least partially around or beside the display area. For example, the section may be defined by one of the sub-bypass lines, especially the second sub-bypass line. The display device may further include a plurality of first horizontal power supply lines which extend in the first direction in the display area and to which a first source voltage is applied, a plurality of second horizontal power supply lines which extend in the first direction in the display area and to which a second source voltage higher than the first source voltage is applied, and a first vertical power supply line extending in the second direction in the display area and disposed to be spaced apart from one end of the second sub-bypass line along the second direction. The first vertical power supply line may be connected to any one of the plurality of first horizontal power supply lines. A first spacing portion disposed between the first vertical power supply line and the one end of the second sub-bypass line of a first bypass line of the plurality of bypass lines overlaps any one of the plurality of second horizontal power supply lines. Each of the second sub-bypass line of the first bypass line and the first vertical power supply line may include a first line portion having a first width, and a second line portion having a second width greater than the first width. The first spacing portion may be
