Patent ID: 8624244

Claim:
A thin film transistor comprising: a gate electrode; a semiconductor layer disposed opposite to the gate electrode with a gate insulating film interposed therebetween; a source electrode placed above the semiconductor layer and electrically connected with the semiconductor layer; and a drain electrode placed above the semiconductor layer and electrically connected with the semiconductor layer, wherein the semiconductor layer includes a light-transmitting semiconductor film and a conductive film placed on the light-transmitting semiconductor film and having a lower light transmittance than the light-transmitting semiconductor film, the conductive film is formed not to protrude from the light-transmitting semiconductor film, the conductive film is formed in separate parts with a channel part interposed between the source electrode and the drain electrode, the source electrode and the drain electrode are connected to the light-transmitting semiconductor film through the conductive film, the conductive film is made of aluminum or an alloy film predominantly composed of aluminum.
