A transflective LCD device includes an array substrate and a color filter. The substrate includes a plurality gate lines, a plurality of common lines, and a plurality of data lines substantially crossing the gate lines to define a plurality of sub-pixel regions. Each sub-pixel region has a reflective area and a transmissive area. Two of the reflective area of two adjacent sub-pixel regions in the same column are juxtaposed to each other. The color filter has a plurality of sub-pixel regions respectively aligned with the sub-pixel regions of the array substrate. The color filter includes an insulating layer disposed on the reflective area of a respective sub-pixel region. An LC layer is disposed between the array substrate and the color filter.

A pixel structure of a transflective liquid crystal display array substrate includes a first patterned conductive layer, a second patterned conductive layer, a transparent patterned conductive layer, a passivation layer, and a patterned reflective metal layer. A first part of the second patterned conductive layer and a first part of the first patterned conductive layer form a first storage capacitor. The first part of the second patterned conductive layer and the transparent patterned conductive layer form a second storage capacitor. The passivation layer is formed to cover the patterned transparent conductive layer and has an opening to expose a part of the patterned transparent conductive layer. The patterned reflective metal layer is formed to cover the passivation layer and electrically connected with the patterned transparent conductive layer via the opening. A method for fabricating the pixel structure of the transflective liquid crystal display array substrate is also disclosed.
