Patent ID: 7777826

Claim:
An active matrix substrate, comprising: a substrate; a plurality of scan lines disposed on the substrate; a plurality of data lines disposed on the substrate; and a plurality of pixel units, each of the pixel units being electrically connected with the one of the scan lines and one of the data lines, at least a part of the pixel units further comprising: a first active device electrically connected with the pixel electrode; a second active device electrically isolated from the pixel electrode, wherein the second active device is a second TFT disposed over the scan line, and the second TFT comprises: a second gate electrode electrically connected with the scan line; a second channel layer, wherein the second channel layer is disposed at the intersection of the scan line and the data line, and the second channel layer is sandwiched between the scan line and the data line; a second source electrode electrically connected with the data line; a second drain electrode electrically isolated from the pixel electrode; and a pixel electrode electrically connected with one of the active devices, wherein the second drain electrode extends from the upside of the scan line to the downside of the pixel electrode along both sides of the scan line.
