The display panel has a first pad area and a second pad area, the first flexible printed circuit film has a third pad area and a fourth pad area, and the second flexible printed circuit film has a fifth pad area and a sixth pad area. The third pad area is bonded to the first pad area, the sixth pad area is bonded to the second pad area, and the fifth pad area is bonded to the fourth pad area. An integrated circuit chip is mounted on the first flexible printed circuit film. ## Claims ### Claim 1 A display device comprising: a display panel comprising: pixels configured to display an image in a display area; a first pad area comprising first pads; a second pad area comprising second pads; and a driver disposed in a non-display area outside the display area, the driver being configured to transmit a gate signal to the pixels; a first flexible printed circuit film comprising: a third pad area comprising third pads bonded to the first pads; a fourth pad area comprising fourth pads; and an integrated circuit chip mounted on the first flexible printed circuit film; and a second flexible printed circuit film comprising: a fifth pad area comprising fifth pads bonded to the fourth pads; and a sixth pad area comprising sixth pads bonded to the second pads, wherein the integrated circuit chip is configured to: transmit a data signal to the pixels via at least one of the third pads; and transmit a gate basic signal to the driver via at least one of the fourth pads and at least one of the sixth pads, the driver being configured to generate the gate signal based on the gate basic signal. ### Claim 2 (depends on 1) The display device of claim 1, wherein the second flexible printed circuit film comprises: a main body part comprising the fifth pad area; and an extension projecting from the main body part, the extension comprising the sixth pad area. ### Claim 3 (depends on 2) The display device of claim 2, wherein the second pad area comprises: a first pad part adjacent to one end of the first pad area; and a second pad part adjacent to another end of the first pad area. ### Claim 4 (depends on 3) The display device of claim 3, wherein: the extension comprises: a first extending part adjacent to one end of the first flexible printed circuit film; and a second extending part adjacent to another end of the first flexible printed circuit film; and the sixth pad area comprises: a first pad part disposed on the first extending part; and a second pad part disposed on the second extending part. ### Claim 5 (depends on 4) The display device of claim 4, wherein: pads of the first pad part of the sixth pad area are bonded to pads of the first pad part of the second pad area; and pads of the second pad part of the sixth pad area are bonded to pads of the second pad part of the second pad area. ### Claim 6 (depends on 1) The display device of claim 1, wherein the second flexible printed circuit film comprises a stabilization circuit, the stabilization circuit being configured to: receive the gate basic signal from at least one of the fifth pads; and transmit at least a portion of the gate basic signal to the at least one sixth pad. ### Claim 7 (depends on 1) The display device of claim 1, further comprising: a power source module configured to: generate a voltage to drive the pixels; and transmit the voltage to the pixels via at least one of the sixth pads. ### Claim 8 (depends on 1) The display device of claim 1, wherein: the display panel further comprises a lighting circuit portion disposed in the non-display area; and the integrated circuit chip is configured to transmit a constant voltage to the lighting circuit portion via at least one of the sixth pads. ### Claim 9 (depends on 1) The display device of claim 1, wherein the first pad area and the second pad area are disposed on a line extending in a first direction. ### Claim 10 (depends on 1) The display device of claim 1, wherein the second flexible printed circuit film comprises: a main body part comprising the fifth pad area; an extension projecting from the main body part; and a connection part extending from the extension, the connection part comprising the sixth pad area. ### Claim 11 (depends on 10) The display device of claim 10, wherein the first pad area and the second pad area are disposed along different lines substantially parallel to one another. ### Claim 12 (depends on 10) The display device of claim 10, wherein the first pad area is disposed farther from the display area than the second pad area. ### Claim 13 A display device comprising: a display panel configured to display an image, the display panel comprising: a first pad area comprising first pads; and a second pad area comprising second pads; a first flexible printed circuit film comprising: a third pad area comprising third pads bonded to the first pads; a fourth pad area comprising fourth pads;
