Liquid crystal display device

Abstract

A liquid crystal display includes: first and second thin film transistors and a compensation transistor formed on a first insulation substrate; a first gray subpixel electrode connected to a drain electrode of the first thin film transistor; a second gray subpixel electrode connected to a drain electrode of the compensation transistor and a drain electrode of the second thin film transistor; and first and second reference voltage lines overlapping at least one of the second gray subpixel electrode and the first gray subpixel electrode, wherein a pixel area occupied by the first gray subpixel electrode and the second gray subpixel electrode is extended in a first direction, the first and second reference voltage lines are extended in a second direction, which is substantially perpendicular to the first direction, to overlap the pixel area, and one of the first and second reference voltage lines is connected to a source electrode of the compensation transistor.

What is claimed is: 
     
         1 . A liquid crystal display, comprising:
 a first substrate;   gate lines disposed on the first substrate and extending in a first direction;   a first thin film transistor, a second thin film transistor, and a compensation transistor which are disposed on the first substrate;   a first gray subpixel electrode connected to a drain electrode of the first thin film transistor;   a second gray subpixel electrode connected to a drain electrode of the compensation transistor and a drain electrode of the second thin film transistor; and   a first reference voltage line and a second reference voltage line each extending in a second direction different from the first direction,   wherein   one of the first and second reference voltage lines is connected to a source electrode of the compensation transistor, and   both the first reference voltage line and the second reference voltage line overlap one of the first gray subpixel electrode and the second gray subpixel electrode.
