Display device
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.
1. A display device comprising:
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, wherein
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,
wherein the opening formed in the pixel isolation insulating film includes a first opening and a second opening adjacent to each other, and
in a portion of the pixel isolation insulating film between the first opening and the second opening, the particles that are contained on a side close to the first opening and the particles that are contained on a side close to the second opening propagate lights at wavelengths different from each other.
2. The display device according to claim 1 , wherein
the particles receive the light emitted from the light-emitting layer and propagate light at a specific wavelength in a direction different from that of the light emitted from the light-emitting layer.
3. The display device according to claim 1 , further comprising a color filter disposed above the light-emitting layer, wherein
the particles receive the light emitted from the light-emitting layer and propagate light of a color corresponding to a color of the color filter in a direction different from that of the light emitted from the light-emitting layer.
4. The display device according to claim 3 , wherein
the pixel isolation insulating film includes a portion that is not covered by the color filter in an area from the opening to a boundary between pixels.
5. The display device according to claim 1 , further comprising a color filter disposed above the light-emitting layer and covering an area of the pixel isolation insulating film from the opening to a boundary between pixels.
6. The display device according to claim 1 , wherein
the particles receive the light emitted from the light-emitting layer and propagate light of a color corresponding to a color of the light emitted from the light-emitting layer in a direction different from that of the light emitted therefrom.
7. The display device according to claim 1 , wherein
the particles include a quantum dot particle.
8. The display device according to claim 1 , wherein
the particles include a metal colloid particle.
9. The display device according to claim 1 , wherein
the particles include a quantum dot particle and a metal colloid particle.
10. The display device according to claim 1 , further comprising a color filter disposed above the light-emitting layer and containing a metal colloid particle.
