Abstract
A liquid crystal display device that is adapted to prevent a short defect between a gate metal film and a data metal film generated from an insulation breakage of an insulating film caused by a static electricity. In the device, a gate metal film is formed at the center of a semiconductor layer with being interleaved with a first insulating film. A connecting metal film is connected to the gate metal film and is formed at a substrate. A second insulating film covers the gate metal film and the connecting metal film and is provided with a first contact hole 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 is provided on the second insulating film contacting the semiconductor layer by way of the first contact hole formed in each side surface of the semiconductor layer. A third insulating film covers the data metal film and the second insulating film and is provided with a second contact hole to expose a part of the data metal film and the center portion of the connecting metal film. A pixel electrode is provided on the third insulating film by way of the second contact hole. The connection parts exposed by the first and second contact holes are separated from each other.
