Embodiment Construction

[0044] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present invention, rather than all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0045] In the embodiment of the present invention, a wave plate with a preset phase difference is set on the side of the color filter substrate close to the liquid crystal layer, so that the phase difference of the liquid crystal layer and the phase difference of the wave plate cancel each other out, thereby ensuring the curvature of the curved surface. When the liquid crystal display panel is in a dark state, no light leakage will occur...

Abstract

The invention discloses a curved liquid crystal display panel and a manufacturing method thereof. The curved liquid crystal display panel mainly comprises a colored film substrate, an array substrate, and a liquid crystal layer, wherein the liquid crystal layer is positioned between the colored film substrate and the array substrate; and a phase retarder film with a preset phase difference is arranged at one side, close to the liquid crystal layer, of the colored film substrate, so that the phase difference of the liquid crystal layer is compensated by the phase difference of the phase retarder film. Therefore, the phenomenon of light leakage when the curved liquid crystal display panel is in a dark state is avoided.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a curved liquid crystal display panel and a manufacturing method thereof. Background technique [0002] The existing curved liquid crystal display device has a high popularity and is favored by more and more consumers. However, when liquid crystal display devices use various methods to realize the curved design of the panel, it will more or less cause stress on the upper and lower glass substrates of the panel, which in turn will cause optical anisotropy of the glass substrate. The polarization state changes when the upper and lower glass substrates are of opposite sex. [0003] For horizontally oriented liquid crystal display panels, such as figure 1 As shown, especially for the In-Plane Switching (IPS) panel and the Advanced Super Dimension Switch (ADS) panel, when the glass substrate is bent, the transmitted light passes through the lower polarizer 101 in sequence , array ...
