However, when the liquid crystal panel is bent to make it in a curved state, since the curved liquid crystal panel has a certain curvature, there will be relative sliding between the curved color filter substrate and the array substrate, so that the black matrix and the data lines no longer correspond , but relative to the radial direction of the curved liquid crystal panel, there is a dislocation, which leads to defects such as light leakage and crosstalk, resulting in distortion of the displayed image of the curved liquid crystal panel and a decrease in optical quality

The invention discloses a manufacturing method of a mask. The manufacturing method includes the steps that an array substrate and a color film substrate are aligned to form a liquid crystal box, wherein the liquid crystal box comprises a preparing surface used for forming a black matrix, and the preparing surface is located on the side, away from the color film substrate, of the array substrate or the side, away from the array substrate, of the color film substrate; the liquid crystal box is bent into a preset shape; the liquid crystal box is lightened; the size of a light leak region is measured on the preparing surface; the corresponding mask is formed according to the size of the light leak region. The invention further discloses a preparing method of a curved surface liquid crystal panel. The mask formed through the manufacturing method of the mask can be used for forming a black matrix of the high-quality curved surface liquid crystal panel.
Description
technical field [0001] The invention relates to the technical field of liquid crystal display panels, in particular to a method for manufacturing a mask plate and a method for manufacturing a curved liquid crystal panel. Background technique [0002] Large size, light and thin, high resolution and high quality picture are the development trend of display at present. Ordinary large-size VA (Vertical Alignment, Vertical Alignment) liquid crystal displays have technical limitations of narrow viewing angle, color shift, and distortion. In order to break through the current technical drawbacks, curved liquid crystal displays have emerged as the times require. Curved liquid crystal displays are gradually favored for their wider viewing angles, reduced distortion for close-up viewing, and product differentiation. [0003] The curved LCD panel is the core component of the curved LCD. The existing manufacturing process of the curved liquid crystal panel is as follows: first, the fl...
