Abstract

The invention relates to a liquid crystal display mother board, an alignment method thereof and a liquid crystal display panel. The liquid crystal display mother board comprises a liquid crystal display panel and an alignment substrate located on one side of the liquid crystal display panel, the liquid crystal display panel comprises an array substrate, an opposite substrate and liquid crystal molecules arranged between the array substrate and the opposite substrate, the array substrate and the opposite substrate are arranged in a box-to-box mode, the array substrate comprises sub-pixels, data lines and grid lines, and the sub-pixels comprise transistors and pixel electrodes. The grid line, the data line and the pixel electrode are correspondingly connected with the grid electrode, the source electrode and the drain electrode of the transistor respectively; the alignment substrate comprises an alignment disc, and the alignment disc comprises a scanning voltage terminal connected with a grid line and a data voltage terminal connected with a data line; when the liquid crystal display mother board is aligned, the data voltage terminal inputs alignment voltage; and the scanning voltage terminal inputs a conduction voltage, so that the alignment voltage is input to the pixel electrode, and the liquid crystal molecules generate a pretilt angle under the action of the alignment voltage. According to the scheme, the alignment quality can be improved.

Description

technical field [0001] The disclosure belongs to the field of display technology, and in particular relates to a liquid crystal display motherboard, an alignment method thereof, and a liquid crystal display panel. Background technique [0002] With the rapid development of the entire TFT (Thin Film Transistor) industry, the market has put forward more high-quality demands for TFT-LCD (Thin Film Transistor Liquid Crystal Display) products, one of which is the demand for large viewing angles. For liquid crystal displays, when observers watch from different angles, the display quality of the picture is inconsistent. Generally, the larger the viewing angle, the worse the picture display quality. In order to ensure a better viewing experience for users, it is necessary to increase the viewing angle of the product, but at present, liquid crystal displays with large viewing angles are prone to disorder the alignment electric field during the alignment process using a common voltage...
