Description

Display Device The present invention relates to a display device. More specifically, the present invention relates to a display device in which a hole is formed within a display area. The display device may include a display area where an image is displayed and a non-display area located outside the display area. Pixels for displaying the image and wiring connected to the pixels may be arranged in the display area. Driving units for driving the pixels and functional modules such as camera modules and sensor modules may be arranged in the non-display area. To reduce dead space caused by non-display areas, a hole may be formed within the display area. A functional module may be placed on the back of the display device to correspond to the hole, and the functional module may detect or recognize objects, users, etc. located on the front of the display device through the hole. When a hole is formed within the display area, wiring placed within the display area may bypass the hole. Accordingly, wiring is placed adjacent to the edge of the hole so that no image is displayed, and a hole edge area surrounding the hole may be formed.
