Claim:
1. A display driver integrated circuit chip comprising: a source driver circuit on a first area of the display driver integrated circuit chip, the source driver circuit being configured to process gamma data corresponding to an image that is to be displayed on a display device and configured to generate a driving signal in response to a control signal and a clock signal; a gamma data manager circuit configured to provide the gamma data to the source driver circuit, the gamma data being generated based on a gamma reference signal that defines a reference voltage level and a gamma information signal that defines the gamma data when compared to the gamma reference signal; a control logic circuit configured to provide the control signal and the clock signal to the source driver circuit; and a memory configured to store operation data used to operate the source driver circuit, the gamma data manager circuit, and the control logic circuit, wherein a gamma signal line used to transmit the gamma data from the gamma data manager circuit to the source driver circuit comprises a first metal line extending in a first direction from the first area to a second area other than the first area and comprises a second metal line extending on the second area in a second direction that is different from the first direction, wherein the second metal line is electrically connected to the first metal line, and wherein a length of the first metal line in the first direction is less than a length of the second metal line in the second direction.
