1. A display device comprising:
a display region in which a plurality of pixels are arranged two-dimensionally on a first face of a substrate; and
a periphery region,
wherein each of the plurality of pixels includes a light-emitting layer and an optical member that refracts light from the light-emitting layer,
wherein the display region includes a first pixel and a second pixel that is located nearer than the first pixel to the periphery region,
wherein in a cross section surface passing through the substrate, the light-emitting layer, and the optical member, the optical member includes a first point that is located nearer than a top of the optical member to the display region and a second point that is located nearer than the top of the optical member to the periphery region;
wherein a height of the first point from the first face is equal to a height of the second point from the first face; and
wherein
a first line is tangent to the optical member at the first point,
a second line is tangent to the optical member at the second point, and
an absolute value of a difference between an angle formed by the first face and the first line and an angle formed by the first face and the second line in a second optical member comprised in the second pixel is larger than an absolute value of a difference between an angle formed by the first face and the first line and an angle formed by the first face and the second line in a first optical member comprised in the first pixel.
