An active device array substrate including a substrate, a plurality of pixels, a plurality of signal lines, and a repairing structure is provided. The substrate has a display region and a periphery region. The pixels are arranged on the display region of the substrate as an array. The signal lines are electrically connected to the pixels and are respectively extended from the display region to the periphery region. The repairing structure is disposed at the periphery region, and which includes a first repairing line, a second repairing line, an electrostatic discharge (ESD) releasing line, and an ESD protector. The first repairing line is intersected with one ends of the signal lines and is electrically floated. The ESD protector is connected between the second repairing line and the ESD releasing line, and the ESD protector is overlapped with and electrically insulated from the first repairing line.

Active device array substrate and repairing method thereof

A thin film transistor array substrate, a photolithography process and a design of a mask thereof are provided. A photoresist layer is formed on a substrate, and a mask is set above the substrate. Then, the display element area of the mask is blocked in order to perform the exposure process to the photoresist layer. After that, the non-display element area of the mask is blocked in order to perform the exposure process to the photoresist layer. Finally, a development process is performed to pattern the photoresist layer. Wherein a plurality of pixel patterns is formed in the photoresist layer corresponding to the display element area, and a plurality of peripheral circuit patterns and a plurality of stitching pixel pattern are formed in the photoresist layer corresponding to the non-display element area. Moreover, each one of the stitching pixel patterns is connected to the corresponding pixel patterns.
