Abstract

A method for manufacturing a display apparatus (10) comprises: step 1: sequentially disposing a gate (13), a scanning line (14), a first insulation layer (15) and a semiconductor layer (16) on a substrate (12); step 2: determining the position of a data line (17) on the semiconductor layer (16), and disposing an etching prevention layer (18) at the position, deviating from the data line (17), on the semiconductor layer (16); step 3, modifying the semiconductor layer (16) in the position of the data line (17),into a conductor; and step 4: disposing a source (19), a drain (20), the data line (17) and a second insulation layer (22) on the semiconductor layer (16). Also provided is repairing method. The repairing method comprises: when a data line (17) is broken, separately connecting segments of the broken data line (17) to a conductor layer below the data line (17) in a melted manner. Also disclosed is a liquid crystal display panel. The display apparatus (10) has high display quality and is easy to repair.

Description

Technical field [0001] The present invention relates to a display device, especially a display device for liquid crystal display. The present invention also relates to a repair method of such a display device, and a liquid crystal display panel including such a 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. The data line is prone to breakage and...
