An integrated circuit device including first to Nth circuit blocks CB1 to CBN disposed along a first direction D1, when the first direction D1 is a direction from a first side of the integrated circuit device toward a third side which is opposite to the first side, the first side being a short side, and when a second direction D2 is a direction from a second side of the integrated circuit device toward a fourth side which is opposite to the second side, the second side being a long side. The circuit blocks CB1 to CBN include a logic circuit block LB, a grayscale voltage generation circuit block GB, data driver blocks DB1 to DB4, and a power supply circuit block PB. The data driver blocks DB1 to DB4 are disposed between the logic circuit block LB and the grayscale voltage generation circuit block GB, and the power supply circuit block PB.
