Abstract
Abstract There is provided a color display device comprising a first substrate provided on the light source side to accept an incident light, a second substrate joined with the first substrate via a space to emit an outgoing light, an electro-optical substance held in the space, a plurality of picture elements arranged in a matrix on the second substrate to modulate an incident light and emit an outgoing light, a plurality of microlenses, arranged on the incident light side of the picture elements, for condensing incident light to individual picture elements and a color filter, arranged on the incident light side of the microlenses, for coloring individual picture elements.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
133 words
A color display device comprising: a first substrate provided on a light source side to accept incident light; a second substrate joined with said first substrate via a space to emit outgoing light; an electro-optical material held in said space; a plurality of picture elements arranged in a matrix on said second substrate to modulate incident light and emit outgoing light; a plurality of microlenses, arranged on an incident light side of said picture elements and formed on the internal surface side of said first substrate, each for condensing incident light to an individual picture element; and a color filter of plural color filter elements, formed at an external surface side of said first substrate on the incident light side of said microlenses, each color filter element for coloring an individual picture element.
Claim 2
Dependent Claim
133 words
