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.
Claims9
A display device comprising:
- a white pixel that emits white light;
- a plurality of chromatic color pixels that emit light of chromatic colors, the chromatic color pixels including a chromatic color pixel that emits first color light and a chromatic color pixel that emits second color light;
- a first reflecting layer disposed on the white pixel and the chromatic color pixels;
- a second reflecting layer disposed on the white pixel and the chromatic color pixels, the second reflecting layer and the first reflecting layer facing each other;
- and
- a light emitting layer disposed on the white pixel and the chromatic color pixels and formed between the first reflecting layer and the second reflecting layer, wherein
- the chromatic color pixel that emits the first color light is different from the chromatic color pixel that emits the second color light in distance between the first reflecting layer and the second reflecting layer, and
- at least one of the second reflecting layer and a layer between the first reflecting layer and the second reflecting layer has a light scattering structure in the white pixel.
