Abstract:
1. A liquid crystal display device comprising: a liquid crystal layer and a color filter layer sandwiched between a first transparent substrate and a second transparent substrate; a plurality of gate lines, a plurality of drain lines which cross the plurality of gate lines in a matrix array and thin film transistors formed corresponding to respective crossing points of the gate lines and the drain lines on the first substrate; pixel regions each of which is surrounded by the neighboring gate lines and the neighboring drain lines, each pixel includes at least a common electrode line and a pixel electrode, wherein the liquid crystal display device comprising a first island-like electrode in the pixel region, includes an opening portion formed in a first insulating film which covers the first island-like electrode, includes a common electrode line which extends in the extending direction of the drain lines, wherein the first island-like electrode and the common electrode line are connected via the opening portion, the first island-like electrode constitutes a lower electrode, and a second island-like electrode which is connected to a source of the thin film transistor and is formed on the first insulating film constitutes an upper electrode thus forming holding capacitance.
