Abstract
To enhance the brightness and contrast of a display, and to enhance the visibility of a color filter, a color filter includes a substrate that transmits light, a reflective layer that is formed on the substrate and includes openings, boundary layers formed on parts of the reflective layer, and a plurality of colored layers that are surrounded by the boundary layers. As the boundary layers, boundary layers that transmit light are formed between colored layers of the same color and boundary layers that do not transmit light are formed between colored layers of different colors.
Claims18
A color filter, comprising:
- a substrate that transmits light;
- a reflective layer that is formed on the substrate and includes openings;
- boundary layers formed on part of the reflective layer;
- and
- a plurality of colored layers surrounded by the boundary layers,
- the boundary layers that are positioned between colored layers of a same color transmitting light and the boundary layers that are positioned between colored layers of different colors do not transmit light,
- wherein at least two of the colored layers are the same color and are separated by a single one of the boundary layers, and
- wherein at least two of the colored layers are differently colored and are separated by a single one of the boundary layers.
