Liquid crystal display device comprising an alignment film having a volume resistivity on one side that is greater than a volume resistivity on another side
Abstract:
A method for fabricating a liquid crystal display device including a TFT substrate having an alignment film formed thereon, an opposing substrate, and a liquid crystal layer sandwiched therebetween. The alignment film on the TFT substrate includes a photolytic polymer made from a first precursor including cyclobutane, and a non-photolytic polymer made from a second precursor. The method includes the steps of depositing a mixture material including the first precursor and the second precursor in which the second precursor settles more on an upper surface of the TFT substrate than the first precursor, imidizing the mixture material, and irradiating the mixture material with ultraviolet light for photo-alignment, and after irradiating, heating the mixture material to form the alignment film.
