1. A display device, comprising:
a plurality of light emitting elements provided above a substrate;
a reflector provided on a light extraction side of the plurality of light emitting elements,
a plurality of color filters provided on the light extraction side of the plurality of light emitting elements, and
a pixel defining film having a side wall disposed between two of the plurality of light emitting elements, wherein
a light reflection surface is formed along the side wall of the pixel defining film,
light emitted from one of the two of the plurality of light emitting elements is reflected toward the reflector by the light reflection surface, and
in a cross-section view, the reflector is above and over the light emitting elements,
wherein a center of the reflector is offset from a center of the one of the two of the plurality of light emitting elements.
