Abstract: The present invention provides a transistor including an oxide semiconductor, which is miniaturized and has excellent electrical characteristics. A transistor is configured such that a source electrode layer and a drain electrode layer with a channel formation region interposed therebetween have regions protruding in a channel length direction at lower end portions thereof, and an insulating layer is provided separately from a gate insulating layer between each of the source and drain electrode layers and a gate electrode layer. The transistor is configured such that a width of each of the source and drain electrode layers is smaller than a width of an oxide semiconductor layer in the channel width direction, so that a portion in which each of the source and drain electrode layers overlaps the gate electrode layer is reduced, thereby reducing a parasitic capacitance. In addition, since the source electrode layer and the drain electrode layer have the regions protruding in the channel length direction at the lower end portions thereof, concentration of an electric field is alleviated, and since the above-described insulating layer is provided, the parasitic capacitance between each of the source and drain electrode layers and the gate electrode layer is reduced.
