The first sub-pixel emits a first color light, and includes first and second sides extending in a third direction inclined at a predetermined angle with the first direction, and third and fourth sides extending in a fourth direction perpendicular to the third direction. The second sub-pixel emits a second color light, and is disposed adjacent to the second side of the first sub-pixel in the fourth direction. The third sub-pixel emits a third color light, and is disposed adjacent to the fourth side of the first sub-pixel in the third direction. The fourth sub-pixel emits the first color light, and is disposed adjacent to the second and third sub-pixels. The spacer is disposed between the first and second sub-pixels and between the third and fourth sub-pixels.
