摘要： PROBLEM TO BE SOLVED: To provide a display element whose optical anisotropy degree is changeable by application of an external field, and which requires weak intensity of an external field necessary for driving. SOLUTION: Each of a pair of substrates is provided with an electrode 4, 5 and a rubbed alignment layer 8, 9 on one surface, while the other surface of each of the substrates 1, 2 is provided with a polarizing plate 6, 7. The substrates 1, 2 are placed so that the surfaces provided with the alignment layers 8, 9 are opposed to each other, and a medium prepared by adding a photopolymerizable monomer and a polymerization initiator to a negative liquid crystalline compound is injected into a material layer 3 as a region held between the substrates. By irradiating the medium with UV rays while keeping the state of the medium exhibiting a liquid crystalline phase, the photopolymerizable monomer is polymerized to form a polymer chain 11.
