Drive circuit including a plurality of transistors characteristics of which are made to differ from one another, and a display apparatus including the drive circuit

摘要

A first transistor and a second transistor which serve as switches are connected with each other in series between a data line and a gate electrode of a third transistor which drives a diode. A characteristic of the first transistor is made to differ in terms of current driving capability from that of the second transistor. A storage characteristic of one of the first transistor and the second transistor is made higher than that of the other transistor whereas the current driving capability of the other transistor is raised, and so that leakage current in the first and second transistors which are connected in series is significantly reduced.
