Abstract

A liquid crystal display device having a color filter comprises a liquid crystal shutter device, at least one color filter layer formed on one surface of the liquid crystal shutter device, and at least one diffusion preventing layer for protecting the color filter layer. The color filter layer is prepared by a photolithographic process comprising the steps of forming a layer being colored of gelatin and the like on one surface of the liquid crystal shutter device, coating a photoresist layer thereon, while illuminating the liquid crystal shutter device by white light from the other surface thereof, applying a voltage to the selected opposed surface thereof, applying a voltage to the selected opposed electrode groups to form a latent image in alignment with the electrode groups by a photochemical action, developing the latent image to form a photomask, and while using this mask as a guide, coloring the layer being colored.
