Display device and method of manufacturing a display device
View Patent ↗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.
1. A method of manufacturing a display device, comprising steps of:
forming a first substrate provided with a display region including a plurality of pixels disposed in a matrix;
forming light-emitting elements corresponding to a first sub-pixel and a second sub-pixel that are included in each of the plurality of pixels of the first substrate;
forming a light-shielding film on a second substrate;
removing, in the second substrate, the light-shielding film provided in a transmission region of the first sub-pixel and forming a color filter that selectively transmits light of a first color in the transmission region;
removing, in the second substrate, the light-shielding film provided in a transmission region of the second sub-pixel adjacent to the first sub-pixel and forming a color filter that selectively transmits light of a second color having a luminosity factor lower than that of the light of the first color in the transmission region; and
bonding the second substrate and the first substrate together using, as references, the position of the transmission region provided in the second sub-pixel and the position of a light-emitting region of the light-emitting element provided in the second sub-pixel formed in the first substrate, wherein
a difference in area between a light-emitting region of the light-emitting element and the transmission region in the second sub-pixel is formed to be 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 method of manufacturing the display device according to claim 1 , wherein
in a mask used in removing the light-shielding film formed in the transmission regions of the first and second sub-pixels, a shape corresponding to the transmission region is circular.
