PURPOSE: A thin film transistor and a display using the thin film transistor are provided to form a body contact region for discharging hot carriers in an active layer to prevent the kink effect. CONSTITUTION: A thin film transistor is formed on an insulating substrate and includes an active layer(30) having a channel region(35), source and drain regions(31). A predetermined voltage is applied to the channel region. The active layer includes a power supply layer(37) and a contact line(77). The power supply layer is separated from the source and drain regions. One side of the power supply layer comes into contact with the channel region. The contact line is connected to the power supply layer to apply the predetermined voltage to the channel region. The power supply layer has a conductivity type opposite to the conductivity type of the source and drain regions and is provided with the same voltage as the voltage applied to the source or drain region.
