Abstract:
1. An active-matrix-type image display apparatus comprising: a plurality of pixel circuits, each of which includes a first distance from an upper surface of the gate electrode to an upper surface of the impurity region is longer than a second distance from an upper surface of the gate electrode to an upper surface of the channel region, and a first thickness of the semiconductor layer in a region under at least one of the source electrode and the drain electrode is thicker than a second thickness of the semiconductor layer in a region between the source electrode and the drain electrode; wherein one of the drain electrode and the source electrode in the second thin film transistor of the switching element is electrically connected to the organic light emitting element; wherein the other of the drain electrode and the source electrode in the second thin film transistor of the switching element is electrically connected to the gate electrode of the driver element.
