Abstract:
1. A thin film transistor matrix device comprising: an insulating substrate; a plurality of thin film transistors arranged on the insulating substrate in a matrix; a plurality of picture element electrodes arranged on the insulating substrate in a matrix to define an image display region, and wherein the picture element electrodes are connected to the thin film transistors; a first conductor formed on the insulating substrate, wherein a portion of the first conductor comprises gate electrodes of the thin film transistors; a first insulating film formed on the first conductor; a second conductor formed on the first insulating film; and a second insulating film formed over the first insulating film and the second conductor; a first contact hole formed, outside the image display region, in the first insulating film and the second insulating film, a second contact hole formed, outside the image display region, in the second insulating film, a conducting connection formed between the first contact hole and the second contact hole, the first conductor is connected to the conducting connection via the first contact hole, and the second conductor is connected to the conducting connection via the second contact hole, and wherein the conducting connection is made of a transparent material, wherein the conducting connection is located in an area between the image display region and an edge of the insulating substrate.
