An integrated circuit device includes first to Nth circuit blocks CB1 to CBN disposed along a direction D1 when a direction from a first side which is a short side of the integrated circuit device toward a third side opposite to the first side is a direction D1 and a direction from a second side which is a long side of the integrated circuit device toward a fourth side opposite to the second side is a direction D2. At least one of the circuit blocks on both ends of the circuit blocks CB1 to CBN is a scan driver block for driving a scan line. Or, the scan driver block SB is disposed along the direction D1 on the side of the first to Nth circuit blocks in the direction D2.
