A light-writing-type liquid crystal element which is provided with carrier-blocking layers that are installed on the transparent electrode side and on the light-shielding layer side of a photoconductive layer and that prevents carriers from entering the photoconductive layer. By adjusting the width of a depletion layer that is formed by the carrier-blocking layers and other factors, the energy-band structure of the photoconductive layer is kept asymmetric so that when a voltage is applied onto the photoconductive layer, the area on the writing-light incident-side of the photoconductive layer receives a higher voltage than that of the area on the liquid-crystal-layer side. Consequently, the photosensitivity of the photoconductive layer is improved, and the resolution as well as the contrast of the element can be improved.
