Electrode Structure of a Transistor, and Pixel Structure and Display Apparatus Comprising the Same

Abstract

An electrode structure of a transistor, and a pixel structure and a display apparatus comprising the electrode structure of the transistor are disclosed. The electrode structure of the transistor comprises a first electrode and a second electrode. The first electrode has at least two first portions and at least one second portion. The first portions are substantially parallel with each other and each has a first width. The second portion has a second width, and connects the substantially parallel first portions to define a space with an opening. The first width is substantially greater than the second width.

What is claimed is: 
     
         1 . An electrode structure of a transistor, comprising:
 a first electrode, having:
 at least two first portions substantially parallel with each other and each of the first portions having a first width; and 
 at least one second portion, having a second width, and connecting the first portions to define a space having an opening; and 
   a second electrode having a body and an end portion, and the end portion via the opening disposed in part of the space;   wherein the end portion has a width substantially greater than a width of the body.   
     
     
         2 . The electrode structure of  claim 1 , wherein a ratio of the width of the end portion and the width of the body ranges from about 0.7 to about 2. 
     
     
         3 . The electrode structure of  claim 1 , wherein the width of the body ranges from about 4 um to about 6 um. 
     
     
         4 . The electrode structure of  claim 1 , wherein the width of the end portion ranges from about 4.2 um to about 8 um. 
     
     
         5 . The electrode structure of  claim 1 , wherein the first width is substantially greater than the second width. 
     
     
         6 . The electrode structure of  claim 1 , wherein a ratio of the first width and the second width ranges from about 1.05 to about 2. 
     
     
         7 . The electrode structure of  claim 1 , wherein the first width is substantially 4 um. 
     
     
         8 . The electrode structure of  claim 1 , wherein the second width ranges from about 2 um to about 3.8 um. 
     
     
         9 . The electrode structure of  claim 1 , wherein the width of the end portion and the width of the body has a difference ranges from about 0.2 um to about 4 um. 
     
     
         10 . The electrode structure of  claim 1 , wherein the width of the end portion is substantially greater than the first width. 
     
     
         11 . The electrode structure of  claim 1 , wherein a ratio of the width of the end portion and the first width ranges from about 1.05 to about 2. 
     
     
         12 . The electrode structure of  claim 1 , wherein the width of the end portion and the first width has a difference ranges from about 0.2 um to about 4 um. 
     
     
         13 . The electrode structure of  claim 1 , wherein the first electrode has a connecting section connected to at least one of the first portions. 
     
     
         14 . The electrode structure of  claim 1 , wherein the first electrode has a connecting section connected to the second portion. 
     
     
         15 . A pixel structure incorporating the electrode structure of the transistor of  claim 1 . 
     
     
         16 . A display apparatus incorporating the electrode structure of the transistor of  claim 1 .
