<p>To suppress the optical leak current Ioff sufficiently and thereby to attain a high ratio of ON/OFF currents, at least one of the shortest distances from an arbitrary intersection of the contour lines of the gate electrode (131) and the drain electrode (141) to the intersections of the contour lines of the gate electrode (131) and the source electrode (151) is longer than the shortest distance between the part of the contour lines of the gate electrode (131) which is superposed on the drain electrode (141) and the part which is superposed on the source electrode (151).</p> |
