PROBLEM TO BE SOLVED: To improve the image quality and to realize a smoothly animation image display by forming a liquid crystal orienting film with low polarization which has a property to relax polarization on the interface with a liquid crystal. SOLUTION: The liquid crystal oriented film is composed of an orienting film which has a property to relax polarization on the interface with a liquid crystal, especially an orienting film having high conductivity. In this case, it is preferable that the liquid crystal orienting film consists of a SiOX oblique vapor deposition film (wherein x is positive number <2) having <=103.3eV bonding energy of the Si2p orbit. The SiOX is more active than SiO2 and shows conductivity so that charges in the orienting film on the liquid crystal-orienting film interface are effectively released through the SiOX to decrease polarization. The polymer orienting film with low polarization consists of, for example, polyvinylalcohol, polyvinylacetate, polyacrylonitrile, polyethylene, and polyisoprene. Thereby, polarization such as electron polarization in the orienting film can be relaxed.
