Liquid crystal display device and method for producing same

A method for producing a liquid crystal display device, comprising:

• step (1) of forming a liquid crystal layer containing liquid crystal molecules and a polarized light-absorbing monomer between a pair of substrates bonded by a sealing material;
• step (2) of forming layers, one between the liquid crystal layer and one substrate and one between the liquid crystal layer and the other substrate, by irradiating the liquid crystal layer with polarized light to dimerize the polarized light-absorbing monomer and phase-separate the resulting dimer from the liquid crystal layer;
• and
• step (3) of forming alignment control layers for controlling alignment of the liquid crystal molecules by irradiating the liquid crystal layer with polarized light, with the temperature of the liquid crystal layer set to TN-I or higher, where TN-I indicates the phase transition temperature between a nematic phase and an isotropic phase of the liquid crystal molecules contained in the liquid crystal layer,
• wherein the polarized light-absorbing monomer has a polarized light-absorbing skeleton and at least two reactive functional groups, and
• the polarized light-absorbing skeleton includes a cinnamoyl skeleton.
