Abstract: A display device includes a substrate, a barrier layer, light-emitting diodes, and lenses. The barrier layer is provided on the substrate. The barrier layer has through holes. The light-emitting diodes are disposed in the through holes. The lenses is disposed at positions of the through holes. Each of the lenses has a first surface and a second surface, the second surface is a convex surface, and height of a top of the convex surface based on the substrate is greater than a height of an upper surface of the barrier layer based on the substrate. The first surface is opposed to the substrate with the light-emitting diode therebetween. The second surface is a back of the first surface.
