Problems solved by technology

[0004] However, due to the manufacturing process, the length of the polarizer in the direction of the extension of the absorption axis can only reach 2.5m. When the extension direction of the absorption axis of the polarizer is parallel to the long side of the liquid crystal display panel (up to 3m), the polarizer It cannot meet the requirements for the use of liquid crystal display panels
However, the absorption axes of the two polarizers installed in the liquid crystal display device must be perpendicular to each other, so that the length of one of the first polarizer and the second polarizer must not meet the size requirements, which restricts large-sized Development of liquid crystal display panel

Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] Large-size display panels can be used in a wide range of applications, for example, they can be used in many fields such as outdoor display and indoor blackboard. At present, the size of the liquid crystal display panel that can be produced can reach 150 inches. However, when the liquid crystal display panel reaches 130 inches, all components and materials in the liquid crystal display panel need to be redeveloped, such as polarizers, backlights and various Diaphragm etc.

[0033] The main problem in the development of large-sized liquid crystal display panels is how to prepare large-sized polarizers. Since the liquid crystal display panel requires two polarizers, and the size of the polarizers needs to meet the requirement of ...

Abstract

The invention discloses a liquid crystal display panel and a display device. The liquid crystal display panel comprises a first polarizer, an array substrate, a liquid crystal layer, a phase adjustinglayer, a color film substrate, a steering layer and a second polarizer which are sequentially stacked, wherein the absorption axis of the first polarizer is parallel to the absorption axis of the second polarizer; the color film substrate is provided with pixel regions with various colors; the phase adjusting layer is configured to adjust the phase difference of light passing through the phase adjusting layer so as to provide light with different phase differences to pixel regions with different colors in the color film substrate, and the larger the wavelength of the color corresponding to the pixel area, the larger the phase difference of the light is; and the steering layer is configured to deflect the polarization direction of the light passing through the phase adjusting layer by 90 degrees. According to the liquid crystal display panel, light leakage of the liquid crystal display panel can be prevented, and the contrast ratio of the liquid crystal display panel is ensured.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a liquid crystal display panel and a display device. Background technique [0002] Due to the advantages of high brightness, small size, low radiation, low energy consumption, and soft picture, the liquid crystal display device has been greatly developed. A liquid crystal display device mainly includes a liquid crystal display panel, a backlight module, and the like. Wherein, the liquid crystal display panel includes a first polarizer, an array substrate, a liquid crystal layer, a color filter substrate and a second polarizer stacked in sequence, and the absorption axes of the first polarizer and the second polarizer are perpendicular to each other. [0003] For a large-sized liquid crystal display panel, for example, a 150-inch liquid crystal display panel, the long side of the panel size is usually required to reach 3m, and correspondingly, the long side of the first polarize...
