An active matrix type display device having a plurality of pixel circuits (1) arranged in a matrix shape. The pixel circuit has: a display device (EL); a drive transistor (M1) of a first conductivity type for controlling a current flowing in the display device; a capacitor (C1) provided at a control electrode of the drive transistor; and a switch (M2a, M2b), connected to the control electrode of the drive transistor, for holding a drive control signal at the capacitor. The switch includes a switching transistor (M2a) of the first conductivity type and a switching transistor (M2b) 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 transitor of the second conductivity type is connected to the control electrode of the drive transistor.
