Abstract: A display device includes a light blocking portion and a slit. A portion of an upper layer electrode overlapping a lower layer electrode is provided with a slit extending along a second direction inclined with respect to a first direction. An inclined portion extending along a third direction inclined toward the same side as the second direction with respect to the first direction is included in an end portion, of outer peripheral end portions of the light blocking portion, adjacent to the slit in the first direction. A second angle of the inclined portion that is an angle formed by the third direction with respect to the first direction is larger than a first angle that is an angle formed by the second direction with respect to the first direction.

Abstract: 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.
