Abstract: The reflecting layer is formed on a white pixel PW and chromatic color pixels PR, PG, and PB. The semitransparent reflecting layer is formed on the white pixel PW and the chromatic color pixels PR, PG, and PB. The semitransparent reflecting layer and the intermediate layer in the white pixel PW constitute the light scattering structure. According to this display device, it is possible to obtain an advantage of a micro-cavity structure and an advantage of the white pixel while suppressing an increase in manufacturing cost.
