A display panel and a device are provided. The display panel includes a first substrate. The first substrate includes a first metal layer and a second metal layer. The first metal layer includes first metal portions. Each of the first metal portions includes a plurality of second sub-portions arranged along a second direction. The second metal layer includes a plurality of data lines. Each of the second sub-portions is disposed between two adjacent data lines. In a top view, the display panel includes a plurality of columns of pixels or a plurality of rows of pixels. Each of two sides of each of the columns of pixels is provided with one of the data lines.

Display panel and device

The present invention provides a broken line repair method of a TFT substrate. The method first finds out a broken line in the TFT substrate and a position of a broken point on the broken line. Then, positions of the passivation layer intersecting with the broken line at two ends of the broken point are processed, respectively to expose a metal layer, where the broken line is. Then, a temporary material layer is covered on the passivation layer and the metal layer which is exposed at the two ends of the broken point. Finally, a metal growing film is formed on the temporary material layer to connect the broken line of the two ends of the broken point. With the temporary material layer, the issue of bad repair result due to the remain of the color resist layer and the folding of the passivation layer can be solved.

Broken line repair method of TFT substrate

Disclosed is a broken line repair method of a TFT substrate. The method first finds out a broken line in the TFT substrate and a position of a broken point on the broken line. Then, positions of the passivation layer intersecting with the broken line at two ends of the broken point are processed, respectively to expose a metal layer, where the broken line is. Then, a metal growing film is formed on the passivation layer and the metal layer which is exposed at the two ends of the broken point. Finally, a protective film is formed on the surface of the metal growing film or the surface of the metal growing film is flattened and modified. By protecting the metal growing film or by flattening and modifying the surface of the metal growing film to reduce the roughness thereof, the breaking of the metal growing film can be prevented.
