Patent ID: 8743328

Claim:
A manufacturing method for a liquid crystal display device, comprising: forming a semiconductor pattern and a metal pattern on a first substrate, the semiconductor pattern including a first portion formed under the metal pattern and a second portion which outwardly extends out from the metal pattern of the first portion; forming a first insulating layer for covering the metal pattern and the semiconductor pattern; etching the first insulating layer in a first region located above the metal pattern and in a second region located above at least the second portion of the semiconductor pattern so as to remove the second portion and form an etched space; filling the etched space with a second insulating layer, and forming an electrode on the second insulating layer; and then providing liquid crystal between the first substrate and a second substrate facing the first substrate, the liquid crystal being surrounded by a seal portion so as to be sealed, wherein the etching comprises etching, in the first region, the first insulating layer to form a through hole for electrical connection to the metal pattern, and etching, in the second region, the first insulating layer and the semiconductor pattern to remove the second portion of the semiconductor pattern, and each side of the metal pattern and the semiconductor pattern facing the etched space is contacted by the second insulating layer.
