。[Claims for Utility Model Registration] The invention comprises a constant current driver transistor array and a metal layer, and one controlled region of each constant current driver transistor constituting the constant current driver transistor array is formed in the metal layer. In the constant current driver IC configured to connect and supply a power supply voltage to each of the constant current driver transistors via the metal layer, the metal layer is arranged in a substantially fan-shaped planar shape with the power supply pad connection part as the center. a constant current driver IC, wherein one controlled region of each of the constant current driver transistors is connected to the metal layer at a peripheral portion of the metal layer.
