Abstract: A display apparatus includes a first substrate, a color filter, a gap maintaining pattern, a column spacer, and a blocking dam. The first substrate includes a display area and a peripheral area surrounding the display area. The color filter is disposed in the display area. The gap maintaining pattern is disposed in the peripheral area in a same layer as the color filter. The column spacer is disposed on the color filter. The blocking dam is disposed in a same layer as the column spacer and overlaps the gap maintaining pattern. The difference between the gap of the first and second substrates in the display area and the gap of the first and second substrates in the peripheral area may be decreased.

Abstract: A display device includes a substrate, a first pixel and a second pixel. Each of the first pixel and the second pixel includes first, second and third light emitting areas. The second light emitting area is disposed adjacent to the first light emitting area in a first direction, and the third light emitting area is disposed adjacent to the first light emitting area in a second direction. The first light emitting area included in the first pixel and the first light emitting area included in the second pixel emit light of different colors, the second light emitting area included in the first pixel and the second light emitting area included in the second pixel emit light of different colors, and the third light emitting area included in the first pixel and the third light emitting area included in the second pixel emit light of different colors.
