Abstract

A transflective liquid crystal device is provided that has red, green and blue colored layers provided in correspondence with a plurality of dot portions, and reflective layers overlapping the colored layers in plan view. In the plurality of dot portions, transparent bank layers and colored layers arranged to fill regions defined by the bank layers are respectively provided, and the forming areas of the bank layers in the respective dot portions are different from each other such that the forming areas of the colored layers in the respective dot portion are different for each color.

Claims (40)

1. An electro-optical device comprising:

colored layers having plural colors provided in correspondence with a plurality of dot portions;

a reflective layer overlapping the colored layers in plan view; and

transparent layers provided in correspondence with the plurality of dot portions, the transparent layers each surrounding a corresponding colored layer in plan view,

the transparent layers in the dot portions having areas which are different from each other such that the colored layer for each color in the dot portions has a different area.

2. The electro-optical device according to claim 1 ,

wherein the colored layers comprise a droplet material.

3. The electro-optical device according to claim 1 ,

wherein the dot portions include transmissive portions and reflective portions, and the reflective layer is disposed in the reflective portions; and

wherein the colored layers are arranged in the transmissive portions, and the transparent layers and the colored layers are arranged in the respective reflective portions.

4. The electro-optical device according to claim 3 ,

wherein the colored layers comprise red, green, and blue colored layers, and wherein a ratio of the areas of the respective transparent layers in the dot portions is:

red:green:blue=1.1 to 1.3:1.3 to 2.5:1.

5. An electro-optical device comprising:

colored layers having a plurality of colors provided in correspondence with a plurality of dot portions;

a reflective layer overlapping the colored layers in plan view; and

transmissive portions and reflective portions for the dot portions, the reflective layer being formed in the reflective portions;

wherein the dot portions have colored layer regions provided with the colored layers and non-colored regions free of the colored layers, the non-colored regions having transparent layers disposed therein, the transparent layers each surrounding a corresponding colored layer;

wherein the colored layer regions are arranged in the transmissive portions of the dot portions, and corresponding non-colored regions and the colored layer regions are arranged in the reflective portions of the dot portions; and

wherein the non-colored regions in the respective dot portions have areas which are different from each other for each color of the colored layers.

6. The electro-optical device according to claim 5 ,

wherein the transmissive portions have areas that are different from each other for each color of the colored layers.

7. The electro-optical device according to claim 6 ,

wherein the colored layers comprise red, green and blue colored layers, and

wherein a ratio of the areas of the transmissive portions is:

red:green:blue=1 to 1.2:1:1 to 1.5.

8. A color filter substrate comprising:

colored layers having plural colors provided in correspondence with a plurality of dot portions;

a reflective layer overlapping the colored layers in plan view; and

transparent layers provided in correspondence with the plurality of dot portions, the transparent layers each surrounding a corresponding colored layer in plan view,

the transparent layers in the dot portions having areas that are different from each other such that the colored layers for each color in the dot portions has a different area.

9. The color filter substrate according to claim 8 , further comprising a reflective layer overlapping the colored layers in plan view.

10. A color filter substrate comprising:

colored layers having plural colors provided in correspondence with a plurality of dot portions;

a reflective layer overlapping the colored layers in plan view; and

transmissive portions and reflective portions in which the reflective layer is formed for the respective dot portions,

wherein the dot portions have colored layer regions in which the colored layers are provided and non-colored regions in which the colored layers are not provided, the non-colored regions having transparent layers disposed therein, the transparent layers each surrounding a corresponding colored layer,

wherein the colored layer regions are arranged in the transmissive portions of the dot portions, and the corresponding non-colored regions and the colored layer regions are arranged in the reflective portions of the dot portions, and

wherein the non-colored regions in the dot portions have areas that are different from each other for each color of the colored layers.

11. An electronic apparatus comprising the electro-optical device according to claim 1 .
