Abstract:
The present disclosure discloses a current-driven display device that uses an internal compensation method and can display a good-quality image with no bright dots that are not included in intended display content. In a pixel circuit of an organic EL display device, a voltage of a gate terminal of a drive transistor is initialized before the voltage of a data signal line is written to a holding capacitor via the drive transistor in a diode-connected state. A drain terminal of a first initialization transistor is connected to an anode electrode of the organic EL element in another pixel circuit adjacent to the drain terminal in a scanning signal line extension direction. In a reset period, a path for applying an initialization voltage to the gate terminal is formed by a second initialization transistor of the other pixel circuit, an initialization connecting line, and the first initialization transistor of the pixel circuit.
