1. A display device comprising:
- a red pixel provided with a red light-emitting element that generates red light;
a green pixel provided with a green light-emitting element that generates green light;
a first blue pixel emitting blue light having a first y-value in an xy chromaticity coordinate system, wherein the first blue pixel is provided with a first blue light emitting element that generates blue light;
a second blue pixel emitting blue light having a second y-value in the xy chromaticity coordinate system different from the first y-value, wherein the second blue pixel is provided with a second blue light emitting element that generates blue light, and wherein the first blue light emitting element and the second blue light emitting element are made of a same material having a same lifetime characteristic and that generates a same blue light; and
a blue color filter provided on a light-extraction side of the first blue pixel that extracts blue light beams from the blue light generated by the first blue light emitting element.

Abstract
Disclosed herein is a display device including: a red pixel configured to be provided with a red light-emitting element that generates red light; a green pixel configured to be provided with a green light-emitting element that generates green light; and two blue pixels configured to be provided with blue light-emitting elements that generate blue light and have the same structure, wherein a color filter is provided on a light-extraction side of at least one of the two blue pixels so that blue light beams having different y-values in an xy chromaticity coordinate system are extracted from the two blue pixels.

12. A method for driving a display device including a red pixel provided with a red light-emitting element that generates red light, a green pixel provided with a green light-emitting element that generates green light, a first blue pixel emitting blue light having a first y-value in an xy chromaticity coordinate system, wherein the first blue pixel is provided with a first blue light emitting element that generates blue light, a second blue pixel emitting blue light having a second y-value in the xy chromaticity coordinate system different from the first y-value, wherein the second blue pixel is provided with a second blue light emitting element that generates blue light, and wherein the first blue light emitting element and the second blue light emitting element are made of a same material having a same lifetime characteristic and that generates a same blue light, a blue color filter provided on a light-extraction side of the first blue pixel that extracts blue light beams from the blue light generated by the first blue light emitting element, the method comprising:
-
driving only the red pixel, the green pixel, and one of the first and second blue pixels for displaying in which colors can be represented by these three pixels; and driving the red pixel, the green pixel, and both of the first and second blue pixels only for displaying in which color representation is impossible unless these four pixels are used.
