PROBLEM TO BE SOLVED: To obtain a color filter having an overcoat layer (OC) which can orient a liquid crystal by rubbing, by adding a liquid crystal orienting ability to a protective film. SOLUTION: The liquid crystal orienting ability is imparted by rubbing an OC of a color filter for a color liquid crystal display device. Namely, this color filter consists of a transparent substrate 2, specified pixel groups 3 formed on the transparent substrate 2, and a protective film 4 formed on the specified pixel groups 3. The protective film 4 has liquid crystal orienting ability. In this case, a three-dimensionally crosslinked resin is preferably used for the protective film 4. In the production of the color filter above described, after the OC is formed, the surface of the OC is subjected to rubbing to give liquid crystal orienting ability. The rubbing treatment is carried out, for example, by using a velvet rubbing cloth such as nylon and rayon wound on a roller and bringing the rotating roller surface into contact with the OC surface to rub. Thus, the liquid crystal molecules are oriented. |
