Liquid crystal display device, manufacturing method and defect repair method

Abstract

The invention discloses a liquid crystal display device, a manufacturing method and a defect repair method. The liquid crystal display device comprises a plurality of data wires and a plurality of first common electrode cut wires. Scanning lines are crossed with the data wires. The first common electrode cut wires are arranged in parallel with the scanning lines and crossed with the data wires inan insulating way. The scanning lines and the data wires define a plurality of pixel units. Each pixel unit comprises a pixel electrode and a first common electrode. The first common electrode comprises a common electrode part of which one end is electrically connected with the first common electrode cut wire, and a redundant part connected with the common electrode part. The redundant parts are connected with the data wires in the insulating way. The pixel unit further comprises an electrified layer and an insulating layer. The electrified layers are positioned on the corresponding first common electrodes and overlapped with the corresponding common electrode parts, and have common voltages. The insulating layers are positioned between the corresponding electrified layers and the corresponding common electrode parts. Normal display can be realized in a repaired pixel area of the liquid crystal display device, a repair range is relatively larger, the types of repairable broken wires are relatively more, and influence on signal transmission is relatively less.

Description

technical field [0001] The invention relates to the field of liquid crystal display, in particular to a liquid crystal display device, a manufacturing method, and a defect repairing method. Background technique [0002] The multimedia technology in modern society is quite developed, most of which benefit from the progress of semiconductor components and display devices. As far as display is concerned, thin film transistor liquid crystal display (TFT-LCD) with some advantages such as high quality, space utilization, and low power consumption has gradually become the mainstream. [0003] In the process of manufacturing thin-film transistor liquid crystal displays, problems such as the quality of deposited film, the cleanliness of the environment, scratches, and equipment will inevitably lead to circuit breaks, including the scanning lines connected to the gates of thin-film transistors, which give pixels Signal lines that supply voltage, etc. Whether it is in the display are...
