Abstract
An integrated image-input type display unit employs a conventional liquid crystal display panel and is capable of optically writing an original image directly at a high resolution into liquid crystal display panel and electrically reading the image. This unit has an image input/output device comprising a liquid crystal cell which contains light-sensitive molecules. The light-sensitive molecules are capable of changing their structure to a first molecular structure when being irradiated with light of a first wavelength range and to a second molecular structure when being irradiated with light of a second wavelength range, and are further capable of changing their alignment in accordance with the structural change of the light-sensitive molecules.
