Abstract: A pixel circuit includes a first and a second subpixel circuits. The first subpixel circuit includes a first and a second light emitters, and a first setter that sets the first and second light emitters to an emissive or a non-emissive state. The second subpixel circuit includes a third and a fourth light emitters, and a second setter that functions in the same manner as the first setter. The pixel circuit is in at least one of a connection different or an emitter number different state. In the connection different state, a connection between the first and second light emitters is a series or a parallel connection and a connection between the third and fourth light emitters is the other connections. In the emitter number different state, the first and second light emitters are emissive wholly or selectively and the third and fourth light emitter is in the opposite manner.

Abstract: A display device includes a plate-like substrate having a first surface and a second surface, pixel units on the first surface, and a power supply voltage feeder on the second surface. The power supply voltage feeder outputs first and second power supply voltages applicable to the pixel units. The second power supply voltage is lower in potential than the first power supply voltage. The display device includes a first wiring conductor electrically connecting the power supply voltage feeder and the pixel units and a second wiring conductor electrically connecting the power supply voltage feeder and the pixel units. At least one of the first or second wiring conductor includes a planar conductive portion covering the first surface. The planar conductive portion includes connectors connected to the power supply voltage feeder on at least two sides of the substrate.

Abstract: A display device includes a substrate including a first surface, a plurality of pixel units on the first surface, and a first side wiring pad located in a first outermost array adjacent to a first side on the first surface and located between adjacent pixel units of the plurality of pixel units in a direction along the first side. A plurality of pixel units in the first outermost array can be arranged in a portion adjacent to an edge on the first surface of the substrate. A joint pixel pitch can thus be easily equalized to a non-joint pixel pitch, although the non-joint pixel pitch is smaller.
