Abstract

Image display device having an electrode forming layer which includes a plurality of gate lines, a plurality of drain lines, a plurality of switching elements and the a plurality of pixel electrodes, and having reference electrode layer between the electrode forming layer and a substrate where the electrode forming layer formed thereon, and the reference electrode layer and the electrode forming layer are insulated by insulating layer.

Claims (18)

1. A liquid crystal display device, comprising:

a first substrate;

a second substrate;

a liquid crystal layer between the first substrate and the second substrate, containing liquid crystal molecules;

a gate line and a drain line;

a pixel electrode and a counter electrode disposed between the first substrate and the liquid crystal layer;

a gate insulation layer formed on the gate line; and

an organic insulation layer disposed between the first substrate and the liquid crystal layer;

wherein the liquid crystal layer is driven by an electric field generated between the pixel electrode and the counter electrode,

wherein the pixel electrode is formed between the liquid crystal layer and the organic insulation layer,

wherein the counter electrode is a planer shape, and the pixel electrode comprises a slit having a first portion, and the first portion is not parallel with the gate line and the drain line,

wherein the counter electrode is connected to an electrically conductive layer,

wherein the organic insulation layer is formed between the counter electrode and the first substrate, and

wherein the counter electrode is connected to the electrically conductive layer via a through hole within the organic insulation layer.

2. A liquid crystal display device according to claim 1 ,
