Abstract

A substrate 201 has a reflective layer 211 thereon having apertures 211 a , and the reflective layer has a color filter 212 thereon having coloring layers 212 r, 212 g, 212 b . One coloring layer at each pixel has a hyperchromic portion 212 c above the corresponding aperture 211 a of the reflective layer 211 , and a hypochromic portion 212 d on the reflective layer 211 . There is a region in which no hyperchromic portion 212 c is disposed above the corresponding aperture 211 a (FIG. 1 (A)) or another region in which no hypochromic portion 212 d is disposed on the reflective layer 211 (FIG. 1 (B)).

Claims (33)

1. An electrooptical device substrate comprising:

a pixel;

a hypochromic portion and a hyperchromic portion having a higher light density than the hypochromic portion; and

a reflective layer disposed in the pixel,

wherein the hypochromic portion overlaps the reflective layer and the hyperchromic portion overlaps an area where the reflective layer is not disposed in the pixel, and

wherein the hyperchromic portion partially overlaps the reflective layer.

2. The electrooptical device substrate according to claim 1 , wherein at least one part of the hypochromic portion overlaps at least one part of the hyperchromic portion.

3. An electrooptical device comprising:

a pixel;

a coloring layer comprising a hypochromic portion and a hyperchromic portion having a higher light density than the hypochromic portion; and

a reflective layer disposed in the pixel,

wherein the hypochromic portion overlaps the reflective layer and the hyperchromic portion overlaps an area where the reflective layer is not disposed in the pixel, and

wherein the hyperchromic portion partially overlaps the reflective layer.

4. The electrooptical device according to claim 3 , wherein at least one part of the hypochromic portion overlaps at least one part of the hyperchromic portion.

5. An electronic apparatus comprising the electrooptical device according to claim 3 .

6. An electrooptical device comprising:

a substrate;

a pixel;

a reflective layer which is disposed in the pixel and which is disposed above the substrate;

a counter substrate disposed so as to oppose the substrate; and

a coloring layer disposed above the counter substrate, the coloring layer comprising a hypochromic portion and a hyperchromic portion having a higher light density than the hypochromic portion,

wherein the hypochromic portion overlaps the reflective layer and the hyperchromic portion overlaps an area where the reflective layer is not disposed in the pixel, and

wherein the hyperchromic portion partially overlaps the reflective layer.

7. The electrooptical device according to claim 6 , wherein at least one part of the hypochromic portion overlaps at least one part of the hyperchromic portion.

8. An electrooptical device comprising:

a pair of substrates;

a pixel;

a reflective layer disposed in the pixel;

a hypochromic layer disposed above one of the pair of substrates; and

a hyperchromic layer which is disposed above the other of the pair of substrates and which has a higher light density than the hypochromic layer,

wherein the hypochromic layer overlaps the reflective layer and the hyperchromic layer overlaps an area where the reflective layer is not disposed in the pixel, and

wherein the hyperchromic layer partially overlaps the reflective layer.

9. The electrooptical device according to claim 8 , wherein at least one part of the hypochromic layer overlaps at least one part of the hyperchromic layer.
