Abstract
A color liquid crystal display includes a color filter for passing light of a specific wavelength formed between one of the inner surfaces of a pair of substrates which face each other. On the color filter is formed a protective film having a double-layered structure of a transparent first insulative film made of an organic material and a transparent second insulative film made of an inorganic material. On the protective film are sequentially formed transparent electrodes made of ITO and an aligning film. Transparent electrodes and an aligning film are also sequentially formed on the other inner surface of the paired substrates. The substrates are joined by a seal mmeber and a pair of polarizing plates are disposed outside of the joined substrates.
