ABSTRACT:
An LCD comprising a first substrate having an inner surface and an outer surface; a green color filter formed on the outer surface of the first substrate; red, green, and blue color filters formed on the inner surface of the first substrate; a second substrate facing the first substrate and having an inner surface and an outer surface; a pixel electrode formed on the inner surface of the second substrate; a common electrode formed on the inner surface of one of the first and second substrates; and a liquid crystal layer disposed between the first substrate and the second substrate is provided. By this structure, a green light having color purity is produced. The manufacturing method of an LCD is simplified by replacing the black matrix with the overlapped color filters.
