Abstract:
A liquid crystal display device having a liquid crystal display panel, said liquid crystal display panel comprising:a plurality of pixels which are disposed in matrix having rows and columns and each of which has at least a thin film transistor (TFT) and a pixel electrode, each said pixel having an opening defining an aperture ratio; a plurality of gate signal lines which extend from a gate signal input portion disposed along a side of said liquid crystal display panel and each of which is coupled with said TFT's in a row of said matrix; auxiliary capacitor portions each additionally coupled with a pixel electrode of one of said pixels, the width of said gate signal line becomes narrower and thereby capacitance of said auxiliary capacitor portions becomes smaller as the distance from said gate signal input portion becomes larger, and the aperture ratio increasing as the capacitance of said auxiliary capacitor portions becomes smaller; capacitance of each of said auxiliary capacitor portions being determined by an area of an opposing portion between a pixel electrode of a pixel and a gate signal line coupled with an adjacent pixel via an interlayer insulating film and a nitride film between said pixel electrode and said gate signal line.
