Abstract
A reflecting layer is provided for each of a white pixel PW and a plurality of chromatic color pixels PR, PG and PB. A semitransparent reflecting layer is provided for each of the white pixel PW and the plurality of chromatic color pixels PR, PG and PB. The distance between the reflecting layer and the semitransparent reflecting layer in the white pixel PW is larger than the largest distance among distances between the reflecting layer and the semitransparent reflecting layer in the chromatic color pixels PR, PG, PB. Such display device can suppress increase in manufacturing cost and obtain both merits of optical micro-cavity structure and of the white pixel.
Claims7
A display device comprising:
- a white pixel that emits white light and;
- a plurality of chromatic color pixels that respectively emit light of a plurality of chromatic colors different from each other, the plurality of chromatic colors including a first color and a second color, wherein
- each of the white pixel and the plurality of chromatic color pixels includes a first reflecting layer and a second reflecting layer facing to the first reflecting layer,
- a distance between the first reflecting layer and the second reflecting layer in the chromatic color pixel that emits light of the first color is different from that of the chromatic color pixel that emits light of the second color, and
- a distance between the first reflecting layer and the second reflecting layer in the white pixel is larger than the largest distance among distances between the first reflecting layer and the second reflecting layer in the respective chromatic color pixels.
