LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR MANUFACTURING LIQUID CRYSTAL DISPLAY DEVICE

WIPO Patent Application WO/2013/002084

A1

The present invention provides a liquid crystal display device that can reduce image burn-in, etc. and maintain voltage retention when light orientation technology and PSA technology are combined. This liquid crystal display device is provided with: a pair of substrates; a liquid crystal layer sandwiched between the pair of substrates; an orientation film that is formed on at least one of the substrates of the pair of substrates; and a polymer layer that is formed on the orientation film and carries out orientation control on liquid crystal molecules. The polymer layer is formed by generating radicals by light absorption by one or more monomers added to the liquid crystal layer and carrying out polymerization. The orientation film is formed from a polymer material, which has a main chain that includes an imide structure and side chains that include an optically reactive functional group, and has undergone optical orientation treatment.
