    Abstract: A display device includes a substrate, a pixel emitting light, a light blocking layer blocking light, a first pixel row comprising a first pixel group and a second pixel group in a first direction in a plan view, and a second pixel row in a second direction that intersects the first direction and comprising a third pixel group and a fourth pixel group in the first direction. The first pixel group includes a first sub-pixel, a second sub-pixel in a third direction from the first sub-pixel, the third direction intersecting the first direction, and a third sub-pixel in the first direction from the first sub-pixel. The third pixel group may include a sixth sub-pixel, a seventh sub-pixel in the third direction from the sixth sub-pixel, and an eighth sub-pixel in the first direction from the sixth sub-pixel. The third pixel group may be surrounded by the light blocking layer.
