Abstract
A light-emitting device includes a plurality of light-emitting elements and a plurality of pixel circuits. The plurality of pixel circuits each includes a drive transistor configured to drive a corresponding one of the plurality of light-emitting elements, a write transistor configured to write a signal to a gate of the drive transistor, and a light emission control transistor configured to control connection between the gate of the drive transistor and a power supply. The light-emitting device includes a first control line for controlling the write transistor, a second control line for controlling the light emission control transistor, a first circuit configured to incline a signal waveform of the first control line, and a second circuit configured to incline a signal waveform of the second control line.
