Liquid crystal display device and manufacturing method thereof

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, a second electrode, an insulation layer disposed between the first electrode and the second electrode, and a first alignment film disposed on the second electrode, and
• the second substrate including an organic planarized layer and a second alignment film formed on the organic planarized layer,
• 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 is a planar shape and the second electrode includes a plurality of slits,
• wherein the first alignment film and the second alignment film comprise, respectively, a photo alignment film formed by irradiation a photo decomposition type insulating film with light, and
• wherein a thickness of the second alignment film is less than a thickness of the first alignment film measured at a transparent area of the pixel.
