ABSTRACT:
A dot matrix display panel with a thin film transistor and the manufacturing method therefor, the panel being so constructed that a gate insulating layer and a semiconductor layer are provided as one laminated film substantially equal in the size thereto on an insulating substrate having a gate electrode and in a region of the substrate except for the peripheral portion thereof, and a source electrode and a drain electrode come into contact with the semiconductor layer in a region covering the gate electrode and gate insulating layer so as to constitute a thin film transistor array substrate, so that a display medium is sandwiched between the array substrate and the substrate having a transparent electrode.
