    Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal device having uniform perpendicular alignment a method and a device for the production of that liquid crystal device, with respect to the production of an electrically controlled birefringence effect (ECB) type perpendicular alignment liquid crystal device. SOLUTION: The liquid crystal device contains liquid crystal molecules 12 having negative dielectric anisotropy and a polyimide 18 for parallel alignment. The method of producing the device includes a process exposing one surface or the both surfaces of a substrate 14 of the liquid crystal device, having the liquid crystal molecules having a negative dielectric anisotropy aligned parallel by the alignment polyimide and to align the liquid crystal molecules in the perpendicular direction. The exposure device used for the exposure is equipped with a filter, so as to cut the light having =600 nm wavelength, to use the light having the wavelength of 400 nm to 600 nm. When a voltage is applied between electrodes 16 of the liquid crystal device, a response time becomes faster.
