Panel for Display Device, Manufacturing Method Thereof and Liquid Crystal Display

Abstract

A method for forming a display device includes forming a first panel and a second panel. The step of forming a first panel includes forming a black matrix over portions of a first substrate, forming a common electrode over the black matrix, and forming a spacer over the common electrode and the black matrix. The step of forming the second panel includes forming a pixel electrode over a second substrate. The first panel and the second panel are disposed over one another such that the pixel electrode faces the common electrode and the black matrix with a liquid crystal layer therebetween. A vertical distance between the first panel and the second panel is determined by thicknesses of the spacer and the black matrix.

1 . A display device, comprising:
 a first panel, the first panel comprising:
 a plurality of color filters, the color filters at least partially overlapping each other; 
 a black matrix overlapping the overlapped portions of the color filters; 
 a common electrode formed on at least a portion of the color filters and the black matrix; and 
 a spacer formed over the overlapped portions of the color filters; 
   a second panel, the second panel comprising:
 a gate line; 
 a data line insulated from the gate line, and crossing the gate line; 
 a thin film transistor connected to the gate line and the data line respectively; 
 a pixel electrode connected to the thin film transistor; and 
 a liquid crystal layer disposed between the first panel and the second panel such that the pixel electrode faces the common electrode with the liquid crystal layer therebetween, 
 wherein a vertical distance between the first panel and the second panel is determined by the spacer, the black matrix and the overlapped portions. 
   
   
   
       2 . The display device of  claim 1 , wherein the common electrode is formed on the black matrix. 
   
   
       3 . The display device of  claim 1 , wherein the second panel further comprising:
 a gate insulating layer formed over the gate line;   a semiconductor pattern formed over the gate insulating layer; and   an ohmic contact pattern formed over the semiconductor pattern.   
   
   
       4 . The display device of  claim 3 , wherein the data line is formed over the ohmic contact pattern and includes a source electrode, a drain electrode and a storage-capacitor conductor. 
   
   
       5 . The display device of  claim 1 , wherein the pixel electrode also faces the black matrix.
