  • Publication number: 20060023145
    Abstract: A transflective liquid crystal display includes a plurality of pixel regions, each pixel region including three subpixel regions with different colors. At least one subpixel region includes a first substrate including a transmissive region and a reflective region; a second substrate disposed on the first substrate; liquid crystal interposed between the first and second substrates; and a color filter formed below the second substrate and including first and second color resists. The whole or most of the first color resist is in the reflective region and the whole or most of the second color resist is in the transmissive region, such that when shifting occurs due to assembly error, the area of the second color resist in the transmissive region remains unchanged. By means of the transflective LCD of the present invention, the chromaticity in the reflective and transmissive regions will reach the target value.
