Abstract
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.

A display device comprising:
- 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) configured to supply a data voltage to the data lines;
- a gate driver IC configured to supply a gate pulse to the gate lines;
- a first flexible film cable bonded to a substrate of the display panel, the first flexible film cable including lines for transmitting gate timing control signals and gate driving powers received from a printed circuit board to the gate driver IC, wherein the first flexible film cable is formed at left and right bezels of the display panel close to the gate driver IC and includes lines connected to a low potential pixel power voltage (EVSS), a gate timing control signal, and gate driving powers;
- a second flexible film cable including lines connected to the EVSS;
- and
- a flexible circuit film on which the first and second flexible film cables and the source driver IC are mounted,
- wherein:
- the flexible circuit film includes lines connected to a high potential pixel power voltage (EVDD),
- the flexible circuit film is disposed between the first and second flexible film cables or between two neighboring second flexible film cables,
- the flexible circuit film is separated from the first and second flexible film cables by a predetermined distance to prevent the EVDD and EVSS being short-circuited, and
- the printed circuit board is disposed on a rear surface of the display panel and is connected to the gate driver IC disposed on a front surface of the display panel by the first flexible film cable and the flexible circuit film which are bent in a U shape, and
- the flexible circuit film has a thickness of 20 μm to 100 μm.
