Active Matrix Type Display Apparatus and a Driving Device of a Load

Abstract

An active matrix type display device includes a plurality of pixel circuits arranged in a matrix shape. The pixel circuit has a display device, a drive transistor of a first conductivity type for controlling a current flowing in the display device, a capacitor provided at a control electrode of the drive transistor, and a switch, connected to the control electrode of the drive transistor, for holding a drive control signal at the capacitor. The switch includes a switching transistor of the first conductivity type and a switching transistor of a second conductivity type, in which one main electrode of the switching transistor of the first conductivity type and one main electrode of the switching transistor of the second conductivity type are connected serially. One of the other main electrode of the switching transistor of the first conductivity type and the other main electrode of the switching transistor of the second conductivity type is connected to the control electrode of the drive transistor.
