ABSTRACT:
In a liquid crystal color display panel comprising a color filter layer superposed on one surface of a liquid crystal shutter device for transmitting or intercepting light by the application of a voltage across electrode groups. This color filter layer is formed of photosensitive emulsion layers which are sensitive to specific color light respectively and provided on a transparent plate. While illuminating the liquid crystal shutter device from the other surface thereof by specific color light sequentially. The voltage is applied across selected opposed electrode groups to form latent images in alignment with the positions of the electrode groups. Then, the latent images are developed to produce colors. In this manner, filter layers are made in alignment with the shutter device.
