Array substrate for in-plane switching mode liquid crystal display device

摘要

An array substrate for a liquid crystal display device includes: a substrate; a gate line and a data line on the substrate; a common line parallel to and spaced apart from the gate line; a thin film transistor connected to the gate line and the data line; a plurality of pixel electrodes in the pixel region; a plurality of common electrodes alternating with the plurality of pixel electrodes; at least one outermost common electrode at an edge portion of the pixel region; a black matrix corresponding to the thin film transistor, the gate line and the data line, the black matrix including an inorganic material and having an open portion; and a color filter layer in the open portion.

1. An array substrate for an in-plane switching mode liquid crystal display device, comprising:
a substrate; a gate line and a data line on the substrate, the gate line and the data line crossing each other to define a pixel region; a common line parallel to and spaced apart from the gate line; a thin film transistor connected to the gate line and the data line; a plurality of pixel electrodes in the pixel region, the plurality of pixel electrodes connected to the thin film transistor and parallel to the data line; a plurality of common electrodes alternating with the plurality of pixel electrodes; at least one outermost common electrode at an edge portion of the pixel region, the at least one outermost common electrode is extended from and has a same layer as the common line and parallel to the data line; at least one auxiliary common electrode having a same layer and a same material as the plurality of common electrodes and electrically connected to the common line via a common line contact hole, wherein the at least one auxiliary common electrode overlaps the at least one outermost common electrode; a black matrix corresponding to the thin film transistor, the gate line and the data line, the black matrix including an inorganic material and having an open portion; and a color filter layer in the open portion.
