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.
