1. A display device comprising:
- a plurality of pixels comprising;
a first pixel comprising a light-emitting element, the light-emitting element having a chromaticity whose x-coordinate in a CIE-XY chromaticity diagram is 0.50 or more;
a second pixel and a third pixel each comprising a light-emitting element, the light-emitting element having a chromaticity whose y-coordinate in the CIE-XY chromaticity diagram is 0.55 or more; and
a fourth pixel and a fifth pixel each comprising a light-emitting element, the light-emitting element having a chromaticity whose x-coordinate and y-coordinate in the CIE-XY chromaticity diagram are 0.20 or less and 0.25 or less, respectively,wherein the first pixel, the second pixel and the fourth pixel are arranged in a first row in a first direction,wherein the third pixel and the fifth pixel are arranged in a second row in the first direction,wherein the first row is adjacent to the second row,wherein the first pixel is adjacent to the second pixel,wherein the second pixel is adjacent to the fourth pixel,wherein the third pixel is adjacent to the fifth pixel,wherein the second pixel and the third pixel are shifted from each other in the first direction,wherein the fourth pixel and the fifth pixel are shifted from each other in the first direction,wherein the fourth pixel and the third pixel overlap each other in a line in a second direction, andwherein the second direction is vertical to the first direction.

Abstract
To improve color reproduction areas in a display device having light-emitting elements. A display region has a plurality of picture elements. Each picture element includes: first and second pixels each including a light-emitting element which has a chromaticity whose x-coordinate in a CIE-XY chromaticity diagram is 0.50 or more; third and fourth pixels each including a light-emitting element which has a chromaticity whose y-coordinate in the diagram is 0.55 or more; and fifth and sixth pixels each including a light-emitting element which has a chromaticity whose x-coordinate and y-coordinate in the diagram are 0.20 or less and 0.25 or less, respectively. The light-emitting elements in the first and second pixels have different emission spectrums from each other; the light-emitting elements in the third and fourth pixels have different emission spectrums from each other; and the light-emitting elements in the fifth and sixth pixels have different emission spectrums from each other.
