Abstract

A color filter substrate includes a color filter layer, a light-transmissive layer and a light-shielding layer. The light-transmissive layer is disposed between pixels and includes a side surface that forms a reflection surface. The light-shielding layer is laminated on the light-transmissive layer.

First claim

What is claimed is:

1. A color filter substrate comprising:
a light-transmissive substrate including an incident surface and an outgoing surface with respect to transmitted light;
a plurality of pixels in which a color filter layer is formed;
a protrusion portion that is disposed between the plurality of pixels on the outgoing surface of the light-transmissive substrate and partitions the color filter layer, the protrusion portion including:
a light-transmissive layer comprising a light transmissive material that forms a reflective side surface, the reflective side surface being formed as an inclined surface and partitioning the color filter layer into at least a first color filter having a first color and a second color filter having a second color filter, the first color filter being directly adjacent to the second color filter; and
a light-shielding layer disposed such that the light-transmissive layer is disposed between the light-transmissive substrate and the light-shielding layer,

wherein
the light-transmissive layer is disposed between at least the first color filter and the second color filter,
the light-transmissive layer disposed between the first color filter and the second color filter includes both a first strip-shaped light-transmissive layer and a second strip-shaped light-transmissive layer parallel to the first strip-shaped light-transmissive layer,
the first strip-shaped light-transmissive layer has a first side surface facing the first color filter and a second side surface facing the second strip-shaped light-transmissive layer, and
the second strip-shaped light-transmissive layer has a first side surface facing the second color filter and a second side surface facing the first strip-shaped light-transmissive layer.

2. The color filter substrate according to claim 1 , wherein a side surface of the light-transmissive layer forms the reflective side surface by laminating the light-shielding layer on the side surface.

3. The color filter substrate according to claim 2 ,
wherein the reflective side surface is formed by laminating the light-shielding layer on the second side surface of the first strip-shaped light-transmissive layer oriented toward the second strip-shaped light-transmissive layer, and
wherein the reflective side surface is formed by laminating the light-shielding layer on the second side surface of the second strip-shaped light-transmissive layer oriented toward the first strip-shaped light-transmissive layer.

4. An electro-optic device comprising:
a counter substrate including the color filter substrate according to claim 1 ;
an element substrate in which a pixel transistor and a pixel electrode are formed; and
a liquid crystal layer interposed between the counter substrate and the element substrate.

5. An electronic apparatus comprising:
the electro-optic device according to claim 4 .
