Liquid crystal display device having uniform feedthrough voltage components
First Claim
1. 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 a matrix having rows and columns and each of which has at least a thin film transistor (TFT) and a pixel electrode;
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; and
auxiliary capacitor portions each additionally coupled with a pixel electrode of one of said pixel, the width of said gate signal line becoming narrower and thereby capacitance of said auxiliary capacitor portions becoming smaller as the distance from said gate signal input portion becomes larger.

Abstract
A liquid crystal display (LCD) device having uniform feedthrough voltage components. The LCD device comprises a LCD panel and a backlight portion for illuminating the LCD panel from the backside. The LCD panel has: a plurality of pixels which are disposed in a matrix having rows and columns and each of which has at least a thin film transistor (TFT) and a pixel electrode; a plurality of gate signal lines which extend from a gate signal input portion disposed along a side of the liquid crystal display panel and each of which is coupled with the TFT'"'"'s in a row of the matrix; and auxiliary capacitor portions each additionally coupled with a pixel electrode of one of the pixel. The width of the gate signal line becomes narrower and thereby capacitance of the auxiliary capacitor portions becomes smaller as the distance from the gate signal input portion becomes larger. Also, luminance of backlight by the backlight portion becomes lower as the distance from the gate signal input portion becomes larger.

9. A liquid crystal display device comprising:
-
(a) a liquid crystal display panel having;
a plurality of pixels which are disposed on a TFT substrate in a matrix having rows and columns and each of which has at least a thin film transistor (TFT) and a pixel electrode;
a plurality of gate signal lines which extend on said TFT substrate 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 pixel, the width of said gate signal line becoming narrower and thereby capacitance of said auxiliary capacitor portions becoming smaller as the distance from said gate signal input portion becomes larger; and
an opposing substrate which opposes to said TFT substrate while keeping a small gap therebetween, said small gap being filled with liquid crystal; and
(b) a backlight portion for illuminating said liquid crystal display panel from the backside thereof, luminance of backlight by said backlight portion becomes lower as the distance from said gate signal input portion becomes larger. - View Dependent Claims (10, 11, 12, 13, 14)
