ABSTRACT:
Disclosed herein is a pixel circuit, including: three pixels to which three primary colors are allocated; and a power supply line. In the pixel circuit, each of the three pixels includes a sampling transistor configured to sample an image signal, a retaining capacitor configured to retain the sampled image signal, a drive transistor configured to output drive current corresponding to the retained image signal within a predetermined light emission period, and a light emitting element configured to emit light in the color allocated to the three pixels in response to the drive current. The pixel circuit includes a single switching transistor disposed commonly to the three pixels for connecting the drive transistors of the pixels to the power supply line within the light emission period.
