Abstract
A pixel circuit disposed in a pixel region including three subpixel regions includes: three light-emitting elements that are disposed in the subpixel regions and have mutually different luminescent colors; one drive circuit that is disposed in a subpixel region serving as a first subpixel region, and supplies drive current to the three light-emitting elements in time division; and a positive power supply line serving as a first power supply line that is disposed in a subpixel region serving as a second subpixel region, and supplies power supply voltage to the drive circuit.

A pixel circuit disposed in a pixel region including three subpixel regions, the pixel circuit comprising:
- three light-emitting elements that are disposed in mutually different subpixel regions among the three subpixel regions and have mutually different luminescent colors;
- one drive circuit that is disposed in a first subpixel region and supplies drive current to the three light-emitting elements in time division, the first subpixel region being any one subpixel region among the three subpixel regions;
- and
- at least one first power supply line that is disposed in a second subpixel region and supplies power supply voltage to the one drive circuit, the second subpixel region being at least one subpixel region different from the first subpixel region among the three subpixel regions.
