A liquid crystal display device includes a first substrate, a second substrate made of plastic and being spaced apart from the first substrate, a thin film transistor on the inner surface of the first substrate, a pixel electrode connected to the thin film transistor, a color filter layer under the pixel electrode, a polarizer on the outer surface of the second substrate, a black matrix on the inner surface of the second substrate and corresponding to the thin film transistor, a common electrode on the black matrix, and a liquid crystal layer between the pixel electrode and the common electrode.
