Embodiment Construction

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. 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.

[0042] Crystals with positive stress optics coefficients and crystals with negative stress optics coefficients behave differently when subjected to tension and compression. Such as image 3 As shown, when the crystal with positive stress optical coefficient is stretched, the fast optical axis is perpendicular to the principal optical axis; as Figure 4 As shown, when the crystal with positive stress optical coefficient is compressed, the fast optical axis is ...

Abstract

The invention discloses a curved surface liquid crystal display panel and a curved surface liquid crystal display device. The curved surface liquid crystal display panel comprises two base plates which are bent towards one direction, wherein liquid crystals fill a space between the two base plates to form a bent liquid crystal layer; an outer plate surface of glass of at least one base plate is covered with a transparent layer, and stress optical coefficients of the glass and the transparent layer of one base plate on the same side of the liquid crystal layer are positive and negative; the outer plate surface of the glass of each base plate is a plate surface far away from the liquid crystals of the glass of the base plate. The curved surface liquid crystal display device comprises the curved surface liquid crystal display panel. The optical rotation effects of the glass and the transparent layer on the same side of the liquid crystal layer are opposite and optical delays of the glass and the transparent layer are mutually cancelled. The display effects of the curved surface liquid crystal display panel and the curved surface liquid crystal display device are greatly improved.

Description

technical field [0001] The invention relates to the technical field of liquid crystal display, in particular to a curved liquid crystal display panel and a curved liquid crystal display device. Background technique [0002] In the flat liquid crystal display panel of the in-plane switching (In Plane Switching, referred to as IPS) mode, in the non-driven state, its liquid crystal molecules have a substantially parallel homogeneous orientation with respect to the plate surface of the substrate, so when light passes through the liquid crystal layer, its There is little change in the direction of polarization. If the polarization directions of the polarizers disposed on the outer surfaces of the two substrates are perpendicular to each other, the liquid crystal display panel displays almost completely black in a non-driven state. [0003] In the liquid crystal display panel, the glass of the color filter substrate and the array substrate is conventionally adopted to have a posi...
