Abstract

A color filter preventing the occurrence of cross-talk between colors while improving light extraction efficiency, a method of manufacturing the color filter, and a light-emitting device are provided. The color filter includes: a plurality of color filter layers for a plurality of colors arranged on a substrate, a plurality of projections arranged in contact with the color filter layers, the projections of which parts on a side closer to the color filter layers are connected to one another; and a reflecting mirror film formed so as to be laid over a side surface of each of the plurality of projections.

Claims (39)

1. A color filter comprising:

a plurality of color filter layers for a plurality of colors arranged on a substrate,

a plurality of projections arranged in direct contact with the color filter layers, the projections of which parts on a side closer to the color filter layers are connected to one another; and

a reflecting mirror film formed so as to be laid over a side surface of each of the plurality of projections.

2. The color filter according to claim 1 , wherein

side surface shapes in all directions of each of the projections are equal to one another.

3. The color filter according to claim 1 , wherein

a side surface of each of the projections is a paraboloidal surface.

4. The color filter according to claim 1 , wherein

side surface shapes viewed from two directions orthogonal to each other of each of the projections are different from each other.

5. The color filter according to claim 1 , wherein

a plane area on a side closer to the color filter layers of each of the projections is equal to or smaller than an opening area of each of the color filter layers.

6. A method of manufacturing a color filter comprising:

forming a plurality of projections on and directly contacting surfaces of a plurality of color filter layers for a plurality of colors formed on a substrate so that parts on a side closer to the color filter layers of the plurality of projections are connected to one another; and

forming a reflecting mirror film on a side surface of each of the plurality of projections.

7. The method of manufacturing a color filter according to claim 6 , wherein

the plurality of projections are formed so that side surface shapes in all directions of each of the projections are equal to one another.

8. The method of manufacturing a color filter according to claim 6 , wherein

a side surface of each of the projections is a paraboloidal surface.

9. The method of manufacturing a color filter according to claim 6 , wherein

the plurality of projections are formed so that side surface shapes viewed from two directions orthogonal to each other of each of the projections are different from each other.

10. The method of manufacturing a color filter according to claim 6 , wherein

a plane area on a side closer to the color filter layers of each of the projections is equal to or smaller than an opening area of each of the color filter layers.

11. A light-emitting device comprising:

a drive panel including a plurality of self-luminous elements and a drive element driving the plurality of self-luminous elements; and

a sealing panel arranged so as to face the drive panel,

wherein the sealing panel includes:

a substrate,

a plurality of color filter layers for a plurality of colors arranged on the substrate,

a plurality of projections arranged in direct contact with the color filter layers, the projections of which parts on a side closer to the color filter layers are connected to one another; and

a reflecting mirror film formed so as to be laid over a side surface of each of the plurality of projections.

12. The light-emitting device according to claim 11 , wherein

side surface shapes in all directions of each of the projections are equal to one another.

13. The light-emitting device according to claim 11 , wherein

a side surface of each of the projections is a paraboloidal surface.

14. The light-emitting device according to claim 11 , wherein

side surface shapes viewed from two directions orthogonal to each other of each of the projections are different from each other.

15. The light-emitting device according to claim 11 , wherein

a plane area on a side closer to the color filter layers of each of the projections is equal to or smaller than an opening area of each of the color filter layers.
