Patent ID: 8339549

Claim:
A liquid crystal display device including a liquid crystal display panel including pixels each including 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 including a first substrate, a second substrate, and a liquid crystal layer provided between the first substrate and the second substrate, the first substrate including the active device, the pixel electrode, the common electrode and a first alignment film, the second substrate including a second alignment film, and the first alignment film and the second alignment film comprising, respectively, a photo alignment film formed by irradiating a photo decomposition type insulating film with light, wherein the second alignment film has a thickness of at least 10 nm and no greater than 50 nm, the thickness of the second alignment being less than a thickness of the first alignment film, wherein the thickness of the first alignment film and the second alignment film are measured at a transparent area of the pixel.
