ABSTRACT:
An active matrix substrate including a substrate, a plurality of scan lines, a plurality of data lines and a plurality of pixel units is provide. All of the scan lines, the data lines, the pixel units are disposed on the substrate. Each of the pixel units is electrically connected with the corresponding scan line and data line. In addition, at least a part of the pixel units further includes a plurality of active units and a pixel electrode. The active devices are respectively electrically connected with the corresponding scan lines and data lines and the pixel unit is electrically connected with one of the active devices. In summary, each of the pixel units of the active matrix substrate provided by the invention includes more than one active device. When an active device is damaged under normal operation, another active device may be employed for repairing the pixel unit.
