Problems solved by technology

[0002] For the traditional optical film process and design used in displays, the process is not only complicated and costly, but also requires the support or protection of the substrate layer to complete the production and design of the optical film. Limit materials and functions; too many substrates not only lead to high material costs, but also directly or indirectly have a great impact on optical properties, and also cause high thickness of optical films
[0003] In addition, since the liquid crystal panel is a non-self-illuminating display panel, the current liquid crystal display device needs a backlight module to provide a backlight source. In addition, the light use efficiency is low. To achieve high image quality, high brightness, low power consumption or high Fine characteristics require a variety of optical films to improve or enhance its optical properties, such as polarizing film, wide viewing angle film, diffusion film, prism film (also known as brightness enhancement film), etc.

Abstract

The invention discloses a luminous optical film, a manufacturing method of the luminous optical film and a liquid crystal display device. The luminous optical film at least is composed of a base material, an alignment layer and a layer of polarized liquid crystal film, wherein, the polarized liquid crystal film comprises liquid crystal and luminous dyestuffs. The alignment layer is arranged at one side of the base material. The polarized liquid crystal film is arranged above the alignment layer. The luminous optical film can be applicable to a polarized film, a compensation film or a color filter. The luminous optical film can give out uniform polarized light owning to the overall arrangement of the liquid crystal. Therefore, a conventional backlight module is not required, thus greatly reducing expenses on the conventional backlight module.
