Display apparatus, a method of manufacturing the same and a color filter
First Claim
1. A display apparatus comprising:
- a pair of substrates comprising a first substrate on a front side and a second substrate on a rear side, disposed in opposite directions from each other;
a first electrode provided in an internal surface of said first substrate;
a second electrode provided in an internal surface of said second substrate;
a color filter provided on said first substrate, and aligned with a pixel formed in a portion in which said first and said second electrodes oppose to each other;
an electro-optical layer disposed between said pair of substrates; and
a reflection layer provided on an internal surface of said second substrate, wherein;
said reflection layer includes a hole provided for each pixel, thereby dividing each pixel in its plane into a light transmission portion which is within the hole and a light reflection portion which is outside the hole; and
said color filter comprises a lamination of a colored layer and a transparent layer, wherein;
said colored layer is formed thinner in said reflection portion than in said transmission portion, and said transparent layer is formed so as to cover a difference in level of said colored layer caused between the transmission portion and the reflection portion.

Abstract
A hybrid type display apparatus capable of maintaining color purity in a case of transmission mode display, and improving lightness of color in a case of reflection mode display is provided. This hybrid type display apparatus is comprised of: a pair of substrates comprising a first substrate on a front side and a second substrate on a rear side, disposed in opposite directions spaced apart from each other; a first electrode provided on an internal surface of the first substrate; a second electrode provided on an internal surface of the second substrate; a color filter provided on the first substrate, aligned with a pixel in a portion between the first electrode and the second electrode spaced apart in the opposite directions from each other; a liquid crystal layer interposed between the first and the second substrates; and a reflection layer provided on the second substrate. The reflection layer has a hole provided for each pixel, which divides a plane of each pixel into a transmission portion within the hole and a reflection portion outside the hole. The color filter comprises a lamination of a colored layer and a transparent layer. The colored layer is formed thinner in the reflection portion than in the transmission layer, and the transparent layer is formed to cover a difference in level between the transmission portion and the reflection portion.

13. A color filter which is formed on a substrate, as colored differently for each pixel, said each pixel being divided, in its plane, into a light transmission region through which a light passes once and a light reflection region through which a light passes twice as an incident light once then as a reflected light, having a lamination structure of a colored layer and a transparent layer, wherein
said colored layer is formed to be thinner in said light reflection region than in said light transmission region; - and
said transparent layer is formed such as to cover a difference in level of said colored layer caused between the light transmission portion and the light reflection portion. - View Dependent Claims (14, 15, 16)
