Title:
COLOR LIQUID CRYSTAL DISPLAY DEVICE AND ITS MANUFACTURE
Document Type and Number:
WIPO Patent Application WO/1997/036205
Kind Code:
A1
Abstract:
A color liquid crystal display device which can display high-quality pictures by preventing the deterioration of the picture quality resulting from light leakage and uneven color tones caused by spacers scattered on a displaying picture element section by resolving such a trouble that the color tone and contrast of a color liquid crystal panel and the picture quality are deteriorated by spacers on the entire surface of a substrate. Since two glass substrates having patterned transparent electrodes are faced to each other with spacer beads in between and spacer beads are distributed on a black matrix formed on a color filter constituting the color liquid crystal panel, no spacer exists in the displaying picture element section. Therefore, the light leakage, etc., caused by the spacers does not occur and a color liquid crystal display which has high cell gap height accuracy and can display high-quality pictures can be obtained.
