Patent ID: 7609354

Claim:
An active matrix substrate comprising: a plurality of scan lines and a plurality of common lines, extending in a first direction on the active matrix substrate; a plurality of signal lines extending in a second direction on the active matrix substrate; pixels disposed in areas defined by the scan lines and the signal lines; bus lines; a terminal area disposed outside the bus lines; a plurality of scan line terminal groups located outside the terminal area; common line terminals provided on either end of each of the scan line terminal groups to be connected to the common lines through the bus lines; and common line lead lines for connecting the facing common line terminals of the adjacent scan line terminal groups and the bus lines, wherein the common line terminals, the common line lead lines, and the bus lines are disposed on an entire first layer of the active matrix substrate, while the plurality of the scan line terminal groups, the plurality of the scan lines, and the plurality of the common lines are disposed on an entire second layer of the active matrix substrate, wherein the first layer is different form the second layer.
