Abstract
A liquid crystal display device has a liquid crystal display panel including pixels each having an active device, a pixel electrode, a common electrode and a liquid crystal layer arranged in a dot matrix array. The liquid crystal display panel has a first substrate, a second substrate, and a liquid crystal layer provided between the first substrate and the second substrate. The first substrate has the active device, the pixel electrode, the common electrode and a first alignment film. The second substrate has a second alignment film. The first alignment film and the second alignment film are respectively a photo alignment film formed by irradiating a photo decomposition type insulating film with light. The second alignment film has a thickness of at least 10 nm and no greater 50 nm and is thinner than the first alignment film.
