Abstract

A display device includes a first substrate provided with a display region including a plurality of pixels arranged in a matrix, each of the plurality of pixels having a plurality of sub-pixels, and a second substrate provided with color filters and a light-shielding film, the color filters including transmission regions selectively transmitting lights of specific colors for the respective sub-pixels, the light-shielding film blocking light. The plurality of sub-pixels include a first sub-pixel provided with the transmission region that transmits light of a first color, and a second sub-pixel provided with the transmission region that transmits light of a second color having a luminosity factor lower than that of the light of the first color. A difference in area between a light-emitting region and the transmission region in the second sub-pixel is smaller than a difference in area between a light-emitting region and the transmission region in the first sub-pixel.

Claims (15)

1. A display device comprising:

a first substrate provided with a display region including a plurality of pixels arranged in a matrix, each of the plurality of pixels having a plurality of sub-pixels; and

a second substrate provided with color filters and a light-shielding film, the color filters including transmission regions selectively transmitting lights of specific colors for the respective sub-pixels, the light-shielding film blocking light, wherein

each of the plurality of sub-pixels includes a light-emitting element,

the plurality of sub-pixels include a first sub-pixel provided with the transmission region that transmits light of a first color, and a second sub-pixel provided with the transmission region that transmits light of a second color having a luminosity factor lower than that of the light of the first color, and

a difference in area between a light-emitting region of the light-emitting element and the transmission region in the second sub-pixel is smaller than a difference in area between a light-emitting region of the light-emitting element and the transmission region in the first sub-pixel.

2. The display device according to claim 1 , wherein

the area of the light-emitting region provided in the first sub-pixel is smaller than the area of the transmission region provided in the first sub-pixel.

3. The display device according to claim 1 , wherein

the area of the transmission region provided in the first sub-pixel is smaller than the area of the light-emitting region provided in the first sub-pixel.

4. The display device according to claim 1 , wherein

the plurality of sub-pixels are disposed in two rows and two columns to constitute one pixel, and

the first sub-pixel and the second sub-pixel are disposed adjacent to each other.

5. The display device according to claim 1 , wherein

the first color is white or green, and the second color is red or blue.
