Abstract: The present invention comprises a first substrate and a second substrate facing each other; a first electrode and a second electrode formed on the facing surface of the first substrate and the second substrate, respectively; an electrical insulating compound layer arranged on the upper part, the lower part, or both parts of at least one among the first electrode and the second electrode; a liquid crystal layer interposed between the first substrate and the second substrate; and first and second orientation stabilizing layers interposed between the first electrode, the second electrode, and the liquid crystal layer, respectively. The first and second orientation stabilizing layers provide a liquid crystal display device including chemical combination formed by the reaction between a hydroxyl (OH) group or NH group formed on the surface of the first electrode, the second electrode, or the electrical insulating compound layer and a compound for forming the orientation stabilizing layer and a manufacturing method thereof. The liquid crystal device has enhanced optical and electrical properties by having a stabilized liquid crystal array, a pretilt angle in a pixel unit, and an increased reaction speed and minimizing defects in operation of the device. Also, the liquid crystal device improves the reliability of the device by being connected to an optical stabilization compound at the surface by chemical combination. There is a benefit to manufacture the liquid crystal display device which uses a high-quality liquid crystal display device or a flexible base substrate requiring a low-temperature process by not including a high-temperature firing process.
