    Abstract: According to one embodiment, a display device includes a base, a plurality of pixels, a power supply line and a power supply line drive circuit. The pixels each include a pixel circuit, a display element including a lower electrode, an upper electrode and an organic layer including a light-emitting layer. The upper electrode is connected to the power supply line that provides a predetermined potential to the upper electrode. The power supply line drive circuit supplies, to the power supply line, a first potential to the upper electrode during a light-emitting period and supplies, to the power supply line, a second potential to the upper electrode during a non-light-emitting period.

    Abstract: A display device includes: pixel electrodes; a first insulation layer having openings corresponding to the respective plurality of pixel electrodes, the first insulation layer being on each periphery of the plurality of pixel electrodes; a second insulation layer on an upper surface of the first insulation layer except for a part thereof; and an electroluminescence layer including light-emitting layers overlapping with the pixel electrodes. Each of the light-emitting layers and another one of the light-emitting layers in different light-emitting colors are adjacent to each other, constituting a pair of different-color-emitting layers. The openings include a pair of different-color openings that overlap with the respective pair of different-color-emitting layers. The second insulation layer is at least between the pair of different-color openings and is adjacent to each of the pair of different-color openings entirely along mutually opposed sides of the pair of different-color openings.

    Abstract: A drive circuit includes a holding capacitor, an element capacitor, and an additional capacitor interposed between one of the source and the drain, and one of the high-potential line and the low-potential line. The drive circuit configured to drive the first light emitter includes a first element capacitor as the element capacitor and a first additional capacitor as the additional capacitor. The driving circuit configured to drive the second light emitter includes a second element capacitor as the element capacitor and a second additional capacitor as the additional capacitor. The first element capacitor is larger in capacitance than the second element capacitor. The first additional capacitor is smaller in capacitance than the second additional capacitor.
