An object is to provide a display device that performs accurate display. A circuit is formed using a transistor that includes an oxide semiconductor and has a low off-state current. A precharge circuit or an inspection circuit is formed in addition to a pixel circuit. The off-state current is low because the oxide semiconductor is used. Thus, it is not likely that a signal or voltage is leaked in the precharge circuit or the inspection circuit to cause defective display. As a result, a display device that performs accurate display can be provided.

The present application discloses a display panel, a repair method for the display panel and a display device, where a repair line includes a first repair point, a second repair point and a third repair point which overlap with a data line, the first repair point is located on a side of a first overlapping area away from the second repair point, the second repair point is located between the first overlapping area and a second overlapping area, and the third repair point is located on a side of the second overlapping area away from the second repair point.

A display device includes a substrate, a scan line disposed on the substrate, a storage line parallel to the scan line and a data line intersecting the scan line and the storage line. First and second transistors are electrically connected to the scan line and the data line. A first pixel electrode is disposed on the first transistor and includes a first stem portion, a first contact portion and a first branch portion. The first branch portion electrically connects the first contact portion to the first stem portion, a second pixel electrode is disposed on the second transistor and includes a second stem portion, a second contact portion and a second branch portion. The second branch portion electrically connects the second contact portion to the second stem portion. A first pattern is disposed between the substrate and the second pixel electrode. The first pattern overlaps the second branch portion.

A repairing structure includes a signal line, a first insulation layer and a second insulation layer. The first insulation layer is disposed on the signal line. The second insulation layer is disposed on the first insulation layer. The first insulation layer includes a first hole, and the first hole overlaps a part of the signal line. The second insulation layer includes a second hole, and the first hole and the second hole at least partially overlap. Therefore, the design of the repairing structure is simple, or the repairing time may be decreased, so as to increase the convenience of use.

A display panel and a display device are provided. A pixel electrode of the display panel includes a pixel electrode body and a pixel electrode extension. The pixel electrode body is positioned within the light-emitting section and the pixel electrode extension is positioned within the light-shielding section. When an insulating layer positioned on an overlapping section is perforated, the pixel electrode extension is electrically connected to the signal electrode of other sub-pixel units via a repair line, thereby solving a technical problem that existing display panels possess a limited effect on repairing bright spots.
