ABSTRACT:
A semiconductor device for being mounted on the display panel board of a display apparatus includes a substrate; a plurality of circuit units disposed on the substrate and including thin-film transistors, the circuit units having respective output terminals; at least one bus interconnect for supplying a voltage to the circuit units; and a power supply feed point for supplying a voltage from an external source to the bus interconnect. The pitch L (m) of the circuit units, the number N of the circuit units, and the resistance R (Q/m) per unit length of the at least one bus interconnect are related to each other as follows:in-line-formulae description="In-line Formulae" end="lead"?R×N2×L≦4×103.in-line-formulae description="In-line Formulae" end="tail"?
