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.
