In one example, a display device may include a display panel having a light guide plate, a printed circuit board (PCB) to generate a driving signal to drive the display panel, a driving integrated circuit (IC) mounted on the display panel to process the driving signal, a timing controller (TCON) integrated into the driving IC to control driving of the display panel, and a flexible printed circuit to electrically connect the driving IC and the PCB. The PCB may be disposed behind the driving IC.
