Display device and method of manufacturing a display device

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.
