Abstract: A display device includes a pixel electrode, a pixel isolation insulating film in which an opening through which the pixel electrode is exposed at a bottom is formed, and a light-emitting layer formed inside the opening. The pixel isolation insulating film contains particles that receive light emitted from the light-emitting layer and propagate light in a direction different from that of the light emitted from the light-emitting layer.

Abstract: Damage of a color filter due to erosion or the like in a process of patterning a light-shielding film to form a black matrix laminated on the color filter of a display device is prevented. Plural color filters are formed on a second substrate correspondingly to pixels. Protection films laminated on upper surfaces of the respective color filters are formed. A light-shielding film is laminated on a surface of the second substrate on which the protection films are formed. The light-shielding film is processed while the protection films are used as damage stoppers, and light-shielding members made of the light-shielding film selectively left along boundaries of the pixels are formed.
