ABSTRACT:
A transflective liquid crystal display device includes a first substrate including transmissive and reflective pixels. Gate and data lines on the first substrate cross each other to define a pixel region, with a thin film transistor at each crossing. The transmissive and reflective pixels correspond to respective pixel regions. A first passivation layer covers the thin film transistor and has a transmissive hole in the transmissive pixel. A first reflector is disposed on the first passivation layer in the reflective pixel. A second passivation layer is disposed on the first reflector and in the transmissive hole. A pixel electrode on the second passivation layer is connected to the thin film transistor. A second substrate opposing the first substrate has a color filter layer on an inner surface thereof. The color filter layer contains R, G and B sub color filters, which each correspond to a pixel region.
