## Abstract

The present invention provides a liquid crystal display panel and liquid crystal display device, which includes data lines, scan lines disposed in a crisscross manner with data lines, pixel electrode disposed within area formed by two adjacent scan lines and two adjacent data lines, and thin film transistor disposed at intersection points of data line and scan line; wherein drain terminal of thin film transistor having extension part acting as repair line for scan line, extension part extending along direction parallel to scan line and an end of extension part away from thin film transistor partially overlapping scan line.

## Claims

### Claim 1

A liquid crystal display panel, which comprises: data lines, scan lines disposed in a crisscross manner with data lines, pixel electrode disposed within area formed by two adjacent scan lines and two adjacent data lines, and thin film transistor disposed at intersection points of data line and scan line; gate terminal of thin film transistor connected to scan line, source terminal of thin film transistor connected to data line and drain terminal of thin film transistor connected to pixel electrode;
wherein long side of pixel electrode being disposed in parallel with scan line, drain terminal of thin film transistor having extension part acting as repair line for scan line, extension part extending along direction parallel to scan line and an end of extension part away from thin film transistor partially overlapping scan line;
wherein the extension part comprising a main part disposed in parallel with scan line and a bending part connected to an end of the main part away from thin film transistor, and the bending part extending towards scan line and partially overlapping scan line; alternatively,
the scan line being disposed with a bump part at an end close to extension part away from thin film transistor, the bump part extending towards extension part and partially overlapping end part of extension part.

### Claim 2 (depends on 1)
