Abstract

The invention relates to a method for manufacturing a display device, a repairing method and a liquid crystal display panel. The method for manufacturing the display device comprises the steps that firstly, a grid electrode, a scanning line, a first insulating layer and a semiconductor layer are sequentially arranged on a substrate; secondly, the position of a data line is determined on the semiconductor layer, and an etching preventing layer is arranged at the position, deviating from the data line, on the semiconductor layer; thirdly, the part, in the position of the data line, of the semiconductor layer is modified into a conductor; fourthly, a source electrode, a drain electrode, the data line and a second insulating layer are arranged on the semiconductor layer. According to the repairing method, when the data line is broken, broken data line segments are connected with a conductor layer below the data line respectively in a melting mode. The display device manufactured through the method is high in display quality and easy to repair.

Description

technical field [0001] The invention relates to a display device, especially a display device for liquid crystal display. The present invention also relates to a repair method of the display device, and a liquid crystal display panel including the display device. Background technique [0002] Generally, a liquid crystal display panel includes a display substrate, an opposite substrate facing the display substrate, and a liquid crystal layer interposed between the display substrate and the opposite substrate. The display substrate includes switching elements and pixel electrodes. A voltage is applied to the liquid crystal layer to control the transmittance of light through the liquid crystal layer, thereby displaying an image. [0003] In the prior art, the switching element is usually a thin film transistor, the source of the thin film transistor is connected to the data line, and the drain is connected to the pixel electrode. Data lines are prone to breakage and are diff...
