Abstract: A display device includes a substrate, a first insulating layer on the substrate and including a flat upper surface, a first conductive layer on the substrate, the first conductive layer including first to third light blocking patterns separated from one another, a second insulating layer on the first conductive layer, and pixel electrodes on the second insulating layer. The pixel electrodes includes a first pixel electrode in a first color pixel and in the first light blocking pattern in a first direction in a plan view, and a second pixel electrode in a second color pixel and covering the second and third light blocking patterns in the first direction, the second insulating layer includes first and second areas respectively overlapping the first and second pixel electrodes, and each of the upper surfaces of the first and second areas includes a curved surface with a concave central portion.
