Abstract

A display apparatus includes a plurality of first pixels each including a first emission layer, a plurality of second pixels each including a second emission layer, and a plurality of third pixels each including a third emission layer. The plurality of first and second pixels are in a first column. A set of a pair of first pixels and a set of a pair of second pixels are alternately positioned in the first column. The plurality of third pixels are in a second column and are in sets each comprising four consecutive third pixels. The first emission layer is integrally formed as a single body in the set of first pixels, the second emission layer is integrally formed as a single body in the set of second pixels, and the third emission layer is integrally formed as a single body in each of sets of third pixels.

First claim

What is claimed is:

1 . A display apparatus comprising:
a plurality of first pixels each comprising a first pixel electrode and a first emission layer, the first emission layer is disposed over the first pixel electrode and emits a first color light; a plurality of second pixels each comprising a second pixel electrode and a second emission layer, the second emission layer is disposed over the second pixel electrode and emits a second color light; and a plurality of third pixels each comprising a third pixel electrode and a third emission layer, the third emission layer is disposed over the third pixel electrode and emits a third color light, wherein the plurality of third pixels are positioned on grid points at regular intervals in a first direction and a second direction, the second direction is perpendicular to the first direction, the plurality of first pixels and the plurality of second pixels are disposed between the plurality of third pixels in inclined columns extending in a third direction at an angle of 45° from the first direction, wherein the plurality of first pixels are arranged in a first inclined column of the inclined columns and the plurality of second pixels are arranged are in a second inclined column of the inclined columns, the first and second inclined columns are alternately arranged, and two first pixels are disposed between adjacent third pixels in each of the first inclined columns, and two second pixels are disposed between adjacent third pixels in each of the second inclined columns.

2 . The display apparatus of claim 1 , wherein the two first pixels are arranged in a fourth direction perpendicular to the third direction, and the two second pixels are arranged in the third direction.

3 . The display apparatus of claim 2 , wherein the first emission layer is integrally formed as a single body in the two first pixels, and the second emission layer is integrally formed as a single body in the two second pixels.

4 . The display apparatus of claim 2 , wherein an area of each of the plurality of third pixels is about twice an area of each of the plurality of first pixels.

5 . The display apparatus of claim 2 , wherein an area of each of the plurality of third pixels is about twice an area of each of the plurality of second pixels.
