ABSTRACT:
A liquid crystal display device having an array substrate of a color filter on a thin film transistor structure and a manufacturing method thereof are disclosed in the present invention. The liquid crystal display device having an array substrate includes an array substrate, a plurality of gate lines and data lines over the substrate, the gate and data lines defining a pixel region, a thin film transistor formed at each crossing region of the gate lines and the data lines, the thin film transistor including a gate electrode, an active layer, a source electrode, and a drain electrode, a black matrix over the thin film transistor, exposing a portion of the drain electrode, a first pixel electrode at the pixel region, contacting the exposed portion of the drain electrode, a color filter on the first pixel electrode at the pixel region, and a second pixel electrode on the color filter, directly contacting the first pixel electrode.
