Description

Display Device The present invention relates to a display device, and more particularly, to a display device capable of securing transmittance in a structure having a camera at the bottom of a panel. With the recent entry into the full-scale information age, the field of displays that visually represent electrical information signals has been rapidly developing. In response to this, various flat display devices with excellent performance characteristics such as thinness, lightness, and low power consumption have been developed and are rapidly replacing existing cathode ray tubes (CRTs). Specific examples of such flat panel display devices include Liquid Crystal Display (LCD), Plasma Display Panel (PDP), Field Emission Display (FED), and Organic Light Emitting Device (OLED). Among these, organic light-emitting diodes (OLEDs) are being considered as competitive applications for their ability to not require a separate light source, enable device compactness, and provide vivid color displays. Meanwhile, organic light-emitting displays are being applied to various display devices such as televisions, smartphones, e-books, monitors, and laptops. Furthermore, when combined with cameras, they perform not only screen display but also the verification and editing of captured images. However, the camera and display panel are formed in separate processes, and the display device is generally implemented by housing the camera in the bezel area on the outer edge of the display panel. In this case, however, the module configuration for driving the camera causes the bezel area on the outer edge of the display panel to protrude or increases the portion that must be covered in the non-display area, requiring an increase in bezel width and thickness. Consequently, the device configuration becomes thicker and detracts from the user's visual perception, leading to efforts to improve this situation.
