We have investigated the effects of ultraviolet light with wavelength of 365nm irradiation on polyimide alignment film. We compared image quality and image sticking of a IPS-LCD before and after irradiation, the experiment showed mura appeared and image sticking became bad through irradiating a certain amount of exposure energy.
