Abstract
A liquid crystal display device including a pair of substrates, a liquid crystal layer including liquid crystal molecules disposed between the substrates, an alignment layer disposed above at least one of the substrates, and a polymer disposed on the alignment layer. The device also includes scanning lines and signal lines, a TFT connected to one of the scanning lines and one of the signal lines, and a pixel electrode connected to the TFT and applying driving voltages to the liquid crystal molecules in an area defined by the pixel electrode. The polymer is formed through polymerization of monomers, different from monomers constituting the alignment layer, by active energy ray irradiation, or by both active energy ray irradiation and heat, and is arranged to align the liquid crystal molecules without rubbing so that the liquid crystal molecules in the area form multiple domains when driving voltages are applied from the TFT.
