A liquid crystal display device is provided to improve aperture ratio, and prevent the response delay by controlling a movement of a liquid crystal display molecule. A first and a second substrates(100,200) are placed having a predetermined interval. A liquid crystal layer(300) is interposed between the first and the second substrate. A first alignment layer(90) is arranged between the first substrate and the second liquid crystal layer. A second alignment layer(160) is arranged between the second substrate and the liquid crystal layer. The first and the second alignment layer comprises a polyimide group, a polyamic acid series, and optical isomerism material.
