<p>PROBLEM TO BE SOLVED: To solve the problem where light from back light is made to enter an amorphous silicon film in a part protruded from a gate electrode from a glass substrate side when a liquid crystal display device is operated, an off- leakage current of a thin film transistor is increased and performance as a pixel switch element is deteriorated. SOLUTION: The smaller one of one edge of a gate electrode which overlaps a source electrode or the other edge of the gate electrode which overlaps with a drain electrode is covered with an amorphous silicon film becoming to a channel.</p> |
