Problems solved by technology
[0003] However, the light guide plate in the liquid crystal display is generally off-white, and the light transmittance is poor, so the liquid crystal display using this light guide plate cannot achieve good light transmittance, so it cannot provide the transparent visual effect required by the user. , which restricts the transparent development of liquid crystal display

The invention provides a light guide plate, a light guide plate assembly and a light guide plate manufacturing method, and relates to the field of liquid crystal display manufacturing, and aims to improve transparency of the light guide plate and the light guide plate assembly. The light guide plate comprises a first transparent substrate and a second transparent substrate, wherein the first transparent substrate comprises a first transparent sub-substrate, a second transparent sub-substrate, and a wide wave reflection high polymer liquid crystal membrane arranged between the first transparent sub-substrate and the second transparent sub-substrate; the second transparent substrate is parallel to the first transparent substrate in a certain distance; the second transparent substrate comprises a third transparent sub-substrate and a fourth transparent sub-substrate; a first transparent electrode is arranged on one side of the third transparent sub-substrate close to the fourth transparent sub-substrate; a second transparent electrode is arranged on one side of the fourth transparent sub-substrate close to the third transparent sub-substrate; and a PDLC (polymer dispersed liquid crystal) membrane is formed between the first transparent electrode and the second transparent electrode. The invention is suitable for the liquid crystal display device using the liquid guide plate or the light guide plate assembly.
Description
technical field [0001] The invention relates to the field of liquid crystal display manufacture, in particular to a light guide plate, a light guide plate assembly and a light guide plate manufacturing method. Background technique [0002] Most of the existing liquid crystal displays rely on the backlight to provide light, but because the backlight usually provides a point light source or a line light source, and the display screen of the liquid crystal display requires the support of a surface light source, so the light guide plate has become an important part of the liquid crystal display. The point light source or line light source provided by the backlight can be converted into a surface light source. With the increasing interest of users in liquid crystal displays, in recent years, in addition to wishing that liquid crystal products, such as liquid crystal displays, can be made lighter and thinner, users also have increasing requirements for transparency of liquid cryst...
