Abstract

A liquid crystal display (LCD) and fabricating method thereof. The LCD includes a first substrate, provided with a plurality of parallel gate lines and a plurality of parallel signal lines, wherein the gate lines and signal lines are perpendicular, and a pixel area is defined by two adjacent gate lines and two adjacent signal lines. A source electrode, electrically connected to one of the adjacent signal lines, and a drain electrode are formed on the pixel area. A first pixel electrode is formed, electrically connected to the drain electrode, on the pixel area. A second substrate is provided a predetermined distance above the first substrate, having a plurality of color-filtering areas, directly above the respective pixel area. A second pixel electrode layer is formed on the second substrate, wherein the part thereof directly above the signal lines is relatively thin.
