A repair method for repairing an active device array substrate is provided. The active device array substrate includes a substrate, scan lines, data lines, active devices, pixel electrodes, and common lines. At least one of the scan line has an open defect. The scan lines and the data lines are intersected to define sub-pixel regions. The active devices are electrically connected with the scan lines and the data lines correspondingly. Each pixel electrode is disposed in one of the sub-pixel regions and electrically connected with one of the active devices. The repair method includes cutting one of the common lines neighboring to the open defect to form a cutting block that is electrically insulated from the common lines; and welding the cutting block, the scan line having the open defect and two active devices located at two opposite sides of the open defect.

A method of forming a common line structure of a display panel includes the following steps. First, provide a substrate, wherein at least one first common section and at least one second common section are disposed on the substrate. Then, form a passivation layer on the substrate, the first common section, and the second common section. Subsequently, form at least one through hole penetrating the passivation layer to at least partially expose the first common section and the second common section. Thereafter, form a connection section on the passivation layer to electrically connect the first common section and the second common section exposed by the through hole.

A gate driver-on-array structure integrated into a display includes a substrate and a gate driver structure formed thereon. The gate driver structure is disposed in a peripheral region of the substrate. The gate driver structure includes a first layer metal pattern, a second layer metal pattern, and an insulating layer disposed therebetween. The first layer metal pattern includes connection nodes. The insulating layer has through holes exposing the connection nodes. The second layer metal pattern fills into the through holes and in contact with the connection nodes of the first layer metal pattern so as to implement necessary electrical connection of the gate driver structure.

A gate driver on array of a display includes a substrate having a peripheral region, and a gate driver on array structure formed in the peripheral region. The gate driver on array structure includes a pull-down transistor, and the pull-down transistor has a gate electrode, an insulating layer, a semiconductor island, a source electrode, and a drain electrode. The semiconductor island extends out of both edges of the gate electrode, and extends out of an edge of the source electrode and an edge of the drain electrode.

A liquid crystal display and a shift register device thereof are provided. The shift register device includes a plurality of shift registers connected in series. In the invention, the channel lengths of the transistors, which are responsible to stop outputting scan signal, in the shift register are manufactured greater than the channel lengths of the transistors, which are responsible to output the scan signal, in the shift register. As a result, the degree of influence that the leakage currents of the N-type transistors being responsible to stop outputting the scan signal in the shift register affect the transistors being responsible to output the scan signal when the transistors being responsible to stop outputting the scan signal are in the sub-threshold region is reduced. And thus each of the shift registers is able to output the scan signal normally.

The thickness of the second thickness region is smaller than that of the first thickness region. In addition, in a gate driver on array (GOA) of a display, it includes a gate driver on array structure with a pull-down transistor. The pull-down transistor has a gate electrode, a semiconductor island, a source electrode and a drain electrode.
