A display device includes a display panel including a pixel array including data lines, gate lines crossing the data lines, and pixels arranged in a matrix form, a source driver integrated circuit (IC) for supplying a data voltage to the data lines, a gate driver IC for supplying a gate pulse to the gate lines, and a first flexible film cable bonded to a substrate of the display panel. The first flexible film cable includes lines for transmitting gate timing control signals and gate driving powers received from a printed circuit board to the gate driver IC. The first flexible film cable has a thickness of about 20 μm to 100 μm.
