Abstract
To provide a color filter substrate and transflective type electro-optical device capable of ensuring both brightness of reflective display and saturation of transmissive display. Also, to reduce the difference in color between reflective display and transmissive display. A reflective layer 211 having openings 211a is formed on a substrate 201, and a color filter 212 having colored layers 212r, 212g, and 212b is formed thereupon. Deep color portions 212c are provided to the colored layer, above the openings 211a of the reflective layer 211.
Claims10
A color filter substrate, comprising:
- a substrate;
- a reflective layer disposed on said substrate, said reflective layer including a transmitting portion capable of transmitting light;
- a colored layer disposed on said reflective layer, said colored layer including a light color portion and a deep color portion, said deep color portion including the same color as the light color portion and a higher color density than said light color portion;
- and
- a transmissive layer disposed above said reflective layer, said transmissive layer including an aperture corresponding to said transmitting portion of said reflective layer, wherein said deep color portion is arranged in a region corresponding to said aperture, said light color portion is arranged in a region adjacent to the region corresponding to said aperture.
An electro-optical device, comprising:
- a first and a second substrate;
- an electro-optical layer containing electro-optical material held between the first and second substrates;
- a reflective layer disposed on said first substrate, said reflective layer including a transmitting portion capable of transmitting light;
- a colored layer disposed on said reflective layer, said colored layer including a light color portion and a deep color portion, said deep color portion including the same color as the light color portion and a higher color density than said light color portion;
- and
- a transmissive layer disposed above said reflective layer, said transmissive layer including an aperture corresponding to said transmitting portion of said reflective layer, said electro-optical layer being thicker in a region corresponding to said aperture than in a region adjacent said region corresponding to said aperture, wherein said deep color portion is arranged in the region corresponding to said aperture, said light color portion is arranged in the adjacent region.
A manufacturing method for a color filter substrate, comprising:
- forming a reflective layer including a transmitting portion capable of transmitting light on a substrate;
- forming a transmissive layer including an aperture corresponding to said transmitting portion above said reflective layer;
- forming a deep color portion of a colored layer in a first region corresponding to said transmitting portion above said reflective layer;
- and
- forming a light color portion of a colored layer in a second region adjacent to said first region, said light color portion including the same color as the deep color portion and a lower color density than said deep color portion.
