Abstract:
A liquid crystal display device includes: a TFT substrate 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 top surface on the TFT substrate side; and a liquid crystal sandwiched between the TFT substrate and the counter substrate. In the liquid crystal display device, the alignment film is configured of a first alignment film layer contacting the liquid crystal layer and having at least one kind of polyimide and a second alignment film layer formed below the first alignment film layer and having at least one kind of polyimide, the first alignment film layer is a material that is enabled to provide liquid crystal alignment regulating force by applying polarized light, and the first alignment film layer and the second alignment film layer contain a common polyimide structure.
