Abstract
Disclosed is a color liquid crystal display in which a shielding member is disposed between a sealing member and a display zone to prevent the liquid crystal layer from being contaminated with liquid crystal-contaminants from the sealing member wherein the shielding member is formed of a material which does not adversely affect the liquid crystal layer. The color liquid crystal display comprises at least a color filter substrate provided with a colored layer with plural colors formed into a predetermined pattern in a display zone on a transparent substrate, a counter electrode substrate disposed opposite to and with a predetermined gap from the color filter substrate, a sealing member disposed outside of the display zone to seal the gap formed between both substrates, a liquid crystal layer formed by filling a liquid crystal material in the gap formed between both substrates and sealed by the sealing member and a shielding member disposed between the sealing member and the display zone and formed of a material which works such that the voltage retention and residual DC (&Dgr;E) of the liquid crystal material after the impurity-extraction treatment is 80% or more and 0.5 V or less r…
