1. A display device comprising:
a plurality of pixel electrodes;
a first insulation layer having a plurality of 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 a part of an upper surface of the first insulation layer; and
a plurality of light-emitting layers overlapping with a corresponding one of the plurality of pixel electrodes,
wherein
one of the plurality of light-emitting layers and another one of the plurality of light-emitting layers in different light-emitting colors are adjacent to each other, constituting a pair of different-color-emitting layers,
the plurality of 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,
the second insulation layer continuously surrounds each of the plurality of openings, and
a portion of the second insulation layer surrounding one of the pair of different-color openings and another portion of the second insulation layer surrounding another one of the pair of different-color openings are formed so as to be connected to each other.
