  • Patent number: 11435792
    Abstract: A display panel and a display device are provided. The display panel has a display area and a fan-out area. The fan-out area and the display area at least partially overlap. By arranging at least one part of the fan-out area in the display area, the display area of the display panel expends to the fan-out area, and therefore the area of the display area of the display panel is increased to reduce the area of the non-display area occupied by the fan-out area. That is, the problem that the non-display area of the display panel is too large is alleviated and the narrow border and full screen technology are further implemented.

  • Patent number: 11404527
    Abstract: Provided is a method for manufacturing a display device that allows easy and reliable repair of a pixel circuit by converting the pixel circuit into a black dot, and a display device. A repair wiring line configured to supply an off potential for turning a drive transistor to an off state is formed superimposed onto an impurity region of a semiconductor layer, interposed between a first compensation transistor and a second compensation transistor having a dual gate structure. The impurity region is irradiated with laser light, thereby connecting the impurity region and the repair wiring line. Then, the second compensation transistor is turned to an on state, thereby setting a potential of a node to the same potential as the off potential and turning the drive transistor to a normally-off state. As a result, a pixel circuit is converted into a black dot and thus repaired.
