LIQUID CRYSTAL DISPLAY DEVICE AND MANUFACTURING METHOD THEREOF

摘要

There is provided a high-quality liquid crystal display device that improves viewing angle characteristics and display contrast in low afterglow. A liquid crystal display device includes: a TFT substrate having a pixel electrode and a TFT and formed with an alignment film on a pixel; a counter substrate disposed opposite to the TFT substrate and formed with an alignment film on a topmost surface on the TFT substrate side; and a liquid crystal sandwiched between the alignment film of the TFT substrate and the alignment film of the counter substrate. The alignment film is a material that is enabled to provide liquid crystal alignment regulating force by applying polarized light. The topmost surface layer of the photo-alignment film has liquid crystal alignment regulating force, and the photo-alignment film has little optical anisotropy.
