Abstract:
1. A liquid crystal display device including a liquid crystal display panel including pixels 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 a first electrode and a second electrode, an insulating layer disposed between the first electrode and the second electrode, and a first alignment film disposed on the second electrode, the second substrate including a second alignment film, and wherein the liquid crystal layer is configured to be controlled by an electric field which is generated between the first electrode and the second electrode, wherein the first electrode and the second electrode are transparent, and the first electrode has a planar shape and the second electrode has a comb teeth plane shape, wherein the first alignment film and the second alignment film comprise, 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 film being less than a thickness of the first alignment film, and wherein the thickness of the first alignment film and the second alignment film are measured at a transparent area of the pixel.
