Abstract
A liquid crystal display element in which a liquid crystal layer is interposed between a pair of electrodes. At least one of the electrodes is light shielding. The liquid crystal display element utilizes a polarized light absorption axis for a pair of polarizers which are arranged on the respective side of the liquid crystal layer. The positioning of the polarizers is selected so that the angle of polarized light causes the liquid crystal layer to have a light shielding quality when no voltage is applied across the pair of electrodes.
