Liquid crystal display panel, liquid crystal waveguide display device and manufacturing method of liquid crystal display panel

Abstract

The invention discloses a liquid crystal display panel, a liquid crystal waveguide display device and a manufacturing method of the liquid crystal display panel. A first base plate, a second base plate and a liquid crystal layer are included, wherein the first base plate and the second base plate are oppositely arranged, and the liquid crystal layer is located between the first base plate and thesecond base plate. The first base plate comprises a first transparent substrate and a first transparent electrode layer formed on one side, close to the liquid crystal layer, of the first transparentsubstrate; the second base plate comprises a second transparent substrate and a second transparent electrode layer formed on one side, close to the liquid crystal layer, of the second transparent substrate; and at least one of the first base plate and the second base plate comprises a refractive index transition layer, the refractive index transition layer is formed between the corresponding transparent substrate and the transparent electrode layer, and the refractive index of the refractive index transition layer is between the refractive index of the corresponding transparent substrate and the refractive index of the transparent electrode layer. By arranging the refractive index transition layer, the refractive indexes of the corresponding transparent substrate and the transparent electrode layer are better matched, an available luminous flux in the liquid crystal display panel is improved, and utilization efficiency of a light source is increased.

Description

technical field [0001] The invention relates to the technical field of transparent display, in particular to a liquid crystal display panel, a liquid crystal waveguide display device and a manufacturing method of the liquid crystal display panel. Background technique [0002] With the increasing development of display technology, various new technologies are constantly emerging. Among them, transparent display technology has gradually entered people's lives. Transparent display devices generally refer to the ability to form a transparent display state so that viewers can see the display in the display device. Display devices for images and scenes behind display devices, such as transparent windows, vending machines, transparent wearables, smart homes, etc. Transparent display technology has broad application prospects. [0003] The light transmittance of a common traditional liquid crystal transparent display device in the prior art is generally lower than 20%, and requires ...

AI Technical Summary

Problems solved by technology

[0005] However, when the liquid crystal waveguide display device in the prior art is displayed, there are still less luminous fluxes in the liquid crystal layer, so that when the liquid crystal molecules scatter light to the incident light, the available The total amount of light is small, and the utilization efficiency of the light source is low, which leads to problems such as insufficient brightness, poor uniformity, and low contrast of the transparent display device, which in turn affects the display effect of the liquid crystal waveguide display device.
