1. A display device comprising a plurality of first sub-pixels, each including a pixel electrode; a plurality of second sub-pixels, each including a pixel electrode; and a plurality of third sub-pixels, each including a pixel electrode, the display device comprising:
a first light-emitting layer that overlaps, in a plan view, with the pixel electrode included in each of the plurality of first sub-pixels;
a second light-emitting layer that overlaps, in the plan view, with the pixel electrode included in each of the plurality of second sub-pixels; and
a third light-emitting layer that overlaps, in the plan view, with the pixel electrode included in each of the plurality of third sub-pixels,
wherein the first light-emitting layer overlaps, in the plan view, with an entirety of the pixel electrode included in each of the plurality of second sub-pixels, and with an entirety of the pixel electrode included in each of the plurality of third sub-pixels, the first light-emitting layer being shaped into a continuous form,
the third light-emitting layer, in the plan view, has a first opening inside a first peripheral end portion of the pixel electrode included in each of the plurality of first sub-pixels, and overlaps with an entire circumference of the first peripheral end portion, and
the third light-emitting layer, in the plan view, has a second opening inside a second peripheral end portion of the pixel electrode included in each of the plurality of second sub-pixels, and overlaps with an entire circumference of the second peripheral end portion.
