Title:
SUBSTRATE FOR LIQUID CRYSTAL DISPLAY DEVICE AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
Japanese Patent JP3458620
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To obtain a display device which has an excellent display grade, substantially prevents the occurrence of problems, such as crosstalks, and has excellent reliability by using a substrate having spacers which are recessed in the sectional shapes of the uppermost layer and are fixed in non-display regions.
SOLUTION: The substrate for the liquid crystal display device having the spacers 16 to 18 which are recessed in the sectional shapes of the uppermost layer in the non-display regions and are fixed is used. The spacers 16 to 18 come into contact with a counter substrate when the liquid crystal display device is manufactured. As a result, the specified gas is held with the counter substrate and liquid crystals are injected into this gap. The height (the height up to the vertex of the recessed shapes when the flat parts near the center of the spacers is determined as a reference) of the recessed shapes is 0.05 to 2μm. If the height is too low, the effect for preventing the display defect, etc., by the nonuniformity of the cell gap is not exhibited. If, conversely, the height is too large, there is a possibility that chipping is induced in the spacers by the load at the time of a rubbing treatment or at the time of assembling the panel.
