Abstract:
1. An integrated circuit device, comprising: first to Nth circuit blocks (N is an integer larger than one) disposed on a surface of the integrated circuit device along a first direction, when the first direction is a direction from a first side of the integrated circuit device toward a third side that is opposite to the first side, and when a second direction is a direction from a second side of the integrated circuit device toward a fourth side that is opposite to the second side, the second side being longer than the first side, the first to Nth circuit blocks including: a logic circuit block that sets adjustment data for adjusting grayscale characteristic; a grayscale voltage generation circuit block that generates grayscale voltages based on the adjustment data for adjusting grayscale characteristic; at least one data driver block that receives the grayscale voltages from the grayscale voltage generation circuit block and drives data lines; and a power supply circuit block that generates a power supply voltage; the at least one data driver block being disposed on the surface of the integrated circuit device between the logic circuit block and the grayscale voltage generation circuit block, and the power supply circuit block, and the logic circuit block supplying the adjustment data for adjusting grayscale characteristic to the grayscale voltage generation circuit block.
