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 objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings.

[0032] The large-size display panel has a wide range of applications, for example, it can be used in many fields such as outdoor display and indoor blackboard. At present, the size of the LCD panel that can be produced can reach 150 inches. However, when the LCD panel reaches 130 inches, various components and materials in the LCD panel need to be redeveloped, such as polarizers, backlight backplanes 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. Because the liquid crystal display panel needs two polarizers, and the size of the polarizers needs to meet the requirements of the long side and the short side of the display panel. Howe...

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 adjustment layer, a color filter substrate, a steering layer and a second polarizer stacked in sequence. The absorption axis of the first polarizer is parallel to the absorption axis of the second polarizer, and the color filter substrate has pixel areas of multiple colors; the phase adjustment layer is configured to adjust the phase difference of the light passing through the phase adjustment layer, so as to transmit light into the color filter substrate The pixel areas of different colors provide light with different phase differences, and the greater the wavelength of the color corresponding to the pixel area, the greater the phase difference of the light; the steering layer is configured to deflect the polarization direction of the light passing through the phase adjustment layer by 90 degrees . The invention can prevent light leakage from the liquid crystal display panel and ensure the contrast of the liquid crystal display panel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a liquid crystal display panel and a display device. Background technique [0002] Liquid crystal display devices have developed rapidly due to their advantages of high brightness, small size, low radiation, low energy consumption, and soft images. The liquid crystal display device mainly includes a liquid crystal display panel and a backlight module. 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-size LCD panel, for example, a 150-inch LCD panel, the long side of the panel size is usually required to reach 3m. Correspondingly, the long side size of the first polarizer and the second polarizer is also required to reach 3m...
