Abstract:
A liquid crystal display device, comprising:a semiconductor layer formed on a substrate; a gate metal film formed at a center of the semiconductor layer, a first insulating film being formed between the semiconductor layer and the gate metal film, the gate metal film exposing two side surfaces of the semiconductor layer; a connecting metal film connected to the gate metal film and formed on the substrate; a second insulating film covering the gate metal film and the connecting metal film and provided with first contact holes to expose a part of each side surface of the semiconductor layer and the center portion of the connecting metal film; a data metal film provided on the second insulating film contacting the semiconductor layer by way of the first contact holes formed to expose a portion of each side surface of the semiconductor layer; a third insulating film covering the data metal film and the second insulating film and provided with a second contact hole to expose a part of the data metal film and the center portion of the connecting metal film; and a pixel electrode provided on the third insulating film by way of the second contact hole, said connection parts exposed by the first and second contact holes being separated from each other.
