Abstract

There is disclosed a thin film transistor, wherein the lengthwise direction of the source is made parallel to that of the gate, and an insulating layer is continuously deposited between double gates and the semiconductor layer to obstruct the pin holes generated during first deposition. Further, between overlapping semiconductor layers there is interposed an insulating layer to prevent short circuit of the electrodes due to the pin holes in the semiconductor layers.
