Abstract:
A display device includes: in a display region, a first scanning control line, a light emission control line, a data signal line, a pixel circuit provided at an intersection of the first scanning control line and the data signal line, and a light-emitting element provided for each of the pixel circuits; and in a non-display region, a first scanning control circuit and a light emission control circuit, wherein each of the pixel circuits includes a drive transistor, a write transistor, and a capacitor, the drive transistor including a first control terminal and a second control terminal positioned above and below a semiconductor layer, the light emission control circuit outputs, to the light emission control line, a light emission control signal that switches between a select state in which the drive transistor is turned on and a non-select state in which the drive transistor is turned off.
