LIQUID CRYSTAL DISPLAY DEVICE AND MANUFACTURING METHOD THEREFOR

摘要

A liquid crystal display device (100) includes a first substrate (10) and a second substrate (20) opposing each other, and a liquid crystal layer (30) provided between the first substrate and the second substrate. At least one of the first substrate and the second substrate includes a horizontal alignment film (12, 22) provided on a side closer to the liquid crystal layer. The liquid crystal display device further includes an alignment sustaining layer (40a, 40b) provided between the horizontal alignment film and the liquid crystal layer, the alignment sustaining layer containing a polymerization product of a photopolymerizable compound. The photopolymerizable compound contains an acrylate group or a methacrylate group. The polymerization product in the alignment sustaining layer contains an acrylate group or a methacrylate group as a residue. The horizontal alignment film contains an acrylate group or a methacrylate group.
