Abstract: A display device includes: a substrate including first and second sides; first and second pixels connected to different scan lines; a light blocking layer defining first and second light emission areas of the first and second pixels; and patterns overlapping the first and second light emission areas and on different layers between a pixel electrode and the substrate. Each emission area is divided into first and second divided areas, between which the first divided area is the closer to the first side. In the first light emission area, an overlap area between the second divided area and the first pattern is larger than an overlap area between the first divided area and the first pattern. In the second light emission area, an overlap area between the first divided area and the first pattern is larger than an overlap area between the second divided area and the first pattern.
