Color filter and liquid crystal display subject to impurity extraction treatment for voltage holding ratio of 80% or more

摘要

An object of the present invention is to provide a color filter for reliably preventing the liquid crystal layer from being contaminated with ionic materials, as well as a liquid crystal display excellent in display qualities. To achieve the object described above, the present invention provides a color filter comprises a substrate, a resin colored layer consisting of a plurality of colors formed in a predetermined pattern on the substrate, and a common transparent electrode layer, said resin colored layer bringing about a voltage holding ratio of 80% or more and a residual DC (DELTAE) of 0.5 V or less in a liquid crystal subjected to treatment for extraction of impurities.
