THIN-FILM TRANSISTOR AND MANUFACTURING METHOD THEREOF
A body layer formed of a semiconductor layer, the body layer comprising, a first region, a second region, and a channel region positioned therebetween; a channel stopper formed on the channel region; source and drain electrodes electrically connected to the first and second regions via first and second contact layers respectively are provided. Each of the first and second contact layers comprises an impurities-containing first amorphous silicon layer; a thickness of each of the first and second regions is less than a thickness of the channel region; and the first and second regions comprise a second amorphous silicon layer containing impurities in a concentration being less than a concentration of impurities contained in the first amorphous silicon layer.

Display device including n-channel transistor including polysilicon
A load, a transistor which controls a current value supplied to the load, a capacitor, a power supply line, and first to third switches are provided. After a threshold voltage of the transistor is held by the capacitor, a potential in accordance with a video signal is inputted and a voltage that is the sum of the threshold voltage and the potential is held. Accordingly, variation in current value caused by variation in threshold voltage of the transistor can be suppressed. Therefore, a desired current can be supplied to a load such as a light emitting element. In addition, a display device with a high duty ratio can be provided by changing a potential of the power supply line.
