| 摘要 |
The present invention discloses a liquid crystal display device, a low temperature poly-silicon display device, and a manufacturing method thereof. The manufacturing method includes: forming a metal shield layer on a substrate; forming a poly-silicon layer above the metal shield layer and insulated from the metal shield layer; and forming a common electrode and a pixel electrode layer above the poly-silicon layer to be insulated from each other to have the pixel electrode layer electrically connected to the poly-silicon layer and the common electrode electrically connected to the metal shield layer. Through the above described method, the present invention reduces the resistance of the common electrode, reduces the delay effect caused by excessively large electrical resistance of the common electrode, reduces the number of masking operation by one, reduces the period of time by which a manufacturing process is completed, lowers down the cost, and increases the throughput.
