An object is to provide a semiconductor device with high aperture ratio or a manufacturing method thereof. Another object is to provide semiconductor device with low power consumption or a manufacturing method thereof. A light-transmitting conductive layer which functions as a gate electrode, a gate insulating film formed over the light-transmitting conductive layer, a semiconductor layer formed over the light-transmitting conductive layer which functions as the gate electrode with the gate insulating film interposed therebetween, and a light-transmitting conductive layer which is electrically connected to the semiconductor layer and functions as source and drain electrodes are included.

If misalignment in a line width direction of an electrode (pad) of a connection terminal is caused in attachment of a substrate and an FPC, a connection area of the FPC terminal and the connection terminal becomes smaller and contact resistance is increased. In particular, an increase in contact resistance of the connection terminal to which a power supply potential serving as a power source is inputted is a cause of defective display. In view of the above, an object of the present invention is to decrease the resistance of a power supply line, to suppress a voltage drop in the power supply line, and to prevent defective display. A connection terminal portion includes a plurality of connection terminals. The plurality of connection terminals is provided with a plurality of connection pads which is part of the connection terminal. The plurality of connection pads includes a first connection pad and a second connection pad having a line width different from that of the first connection pad. Pitches between the plurality of connection pads are equal to each other.
