Patent ID: 8199309

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; common line lead lines for connecting the facing common line terminals of the adjacent scan line terminal groups and the bus lines; and a plurality of connecting portions arranged between the bus lines and the common line lead lines on a same layer as the bus line, wherein the bus lines and the plurality of connecting portions are disposed on an entire first layer of the active matrix substrate, while the common line terminals, the common line lead lines, the plurality of scan line terminal groups, and the plurality of scan lines are disposed on an entire second layer of the active matrix substrate, wherein the first layer is different from the second layer, wherein a conductive material which permits the passage of ultraviolet rays is employed to form lead lines for the common line, which are provided in a sealing area wherein an ultraviolet cured sealing material for attaching the substrate with an opposed substrate is to be applied or written.
