Abstract
A reflective layer 212 having an aperture 212a for each pixel is formed on a first substrate 211, and a colored layer 214 for constituting a color filter is formed thereon. A surface protection layer 215 is formed on the colored layer 214, and a transparent electrode 216 is formed further thereon. The colored layer 214 is constituted so as to cover the aperture 212a in a two-dimensional direction, but overlaps only a part of a reflection surface in the pixel in a two-dimensional direction.
Claims16
An electro-optical device comprising:
- a pair of substrates;
- an electro-optical substance layer disposed between the pair of substrates;
- a first pixel and a second pixel;
- a first colored layer disposed in the first pixel and a second colored layer disposed in the second pixel, the second colored layer having a different color than the first colored layer;
- and
- a first reflective layer disposed in the first pixel and a second reflective layer disposed in the second pixel;
- the first pixel including a first light transmitting region where the first reflective layer is not disposed in the first pixel;
- wherein the first colored layer is disposed in the first light transmitting region and overlaps less than an entirety of the first reflective layer;
- and
- wherein the first colored layer overlaps a greater two-dimensional area of the first reflective layer in plan view than a two-dimensional area of the second reflective layer overlapped by the second colored layer in plan view.

A color filter substrate comprising:
- a substrate;
- a plurality of pixels;
- a first colored layer having a first color disposed in a first pixel and a second colored layer having a second color that is different than the first color disposed in a second pixel;
- a first reflective layer disposed in the first pixel and a second reflective layer disposed in the second pixel;
- and
- a first light transmitting region where the first reflective layer is not disposed in the first pixel and a second light transmitting region where the second reflective layer is not disposed in the second pixel;
- wherein the first colored layer overlaps less than an entirety of the first reflective layer and the second colored layer overlaps less than an entirety of the second reflective layer;
- wherein the first colored layer overlaps a greater two-dimensional area of the first reflective layer in plan view than a two-dimensional area of the second reflective layer overlapped by the second colored layer in plan view.
