Abstract

The invention provides a display substrate, a display device and a preparation method of the display substrate and relates to the technical field of liquid crystal display. The display substrate comprises a base body, a scan short-circuit rod testing line and a data short-circuit rod testing line, wherein the scan short-circuit rod testing line and the data short-circuit rod testing line are arranged on one side of the base body. The cut portions of the scan short-circuit rod testing line and the data short-circuit rod testing line are located on the same layer of one side of the base body. In the mode, the technical problem that in the prior art, short-circuit rod zones cannot be disconnected through laser cutting at a time due to different materials for the cut portions of the scan-side and data-side short-circuit rod zones can be effectively solved.

Description

Technical field [0001] The present invention relates to the field of liquid crystal display technology, and in particular to a method for preparing a display substrate, a display device and a display substrate. Background technique [0002] In the shorting bar (shorting bar) area of ​​the liquid crystal panel in the prior art, the function and defect of the panel are detected by the shorting bar. [0003] The existing wiring method of the shorting bar area is to short the R (red, red), G (green, green), and B (blue, blue) signals of the source side data test line, respectively, and connect the Gate (Gate) side Odd (odd) and Even (even) signals are shorted together. In this way, after the liquid crystal panel is tested, the shorting bar area needs to be cut off by laser cutting. [0004] See figure 1 , figure 1 It is a schematic diagram showing the scanning shorting bar area of ​​the substrate in the prior art. The figure shows the gate side scanning metal traces 101-104, the shorti...
