ABSTRACT:
A drive current value is regulated by a current value regulator circuit of a current drive circuit provided externally of each pixel circuit, so that control lines for a program control provided in order to unify operating threshold values of drive transistors becomes unnecessary. Therefore, the number of transistors of each pixel circuit can be reduced and the circuit size of each pixel circuit can be reduced thereby.
