Abstract: Exfoliation of an etching stopper is prevented. A color filter of the present invention includes an inorganic protection film (etching stopper) composed mainly of SnO2.

Since the inorganic protection film and the transparent electrode can be formed in the same film forming chamber, the time required to produce the color filter can be shortened as compared to in the conventional technique.
