PROBLEM TO BE SOLVED: To provide a liquid crystal display element using a nematic liquid crystal, which is easily fabricated, which has a memory property and a wide viewing angle display characteristic compatible with each other, which is highly precise and which has a wide viewing angle and low power consumption. SOLUTION: In the liquid crystal display element using the nematic liquid crystal, which has: a pair of transparent substrates SUB1, SUB2; a liquid crystal layer LCL disposed between the pair of substrates SUB1, SUB2; a group of electrodes for applying an electric field with a component nearly parallel to surfaces of the substrates to the liquid crystal layer LCL; and an alignment layer, subjected to liquid crystal alignment control treatment in two directions, disposed between the liquid crystal layer LCL and at least one out of the pair of substrates SUB1, SUB2, the liquid crystal alignment control treatment of the alignment layer is irradiation treatment with light generating a chemical reaction of the alignment layer on the substrate surface as linearly polarized light, and the alignment layer is composed of a photo-reactive material of which the direction to control liquid crystal alignment is that corresponding to a polarization direction of linearly polarized light of final irradiation with respect to multiple times of linearly polarized light irradiation.
