Embodiment 1

[0045] figure 1 It is a schematic structural diagram of the liquid crystal display of this embodiment, and the liquid crystal display mainly includes a backlight 210 , a lower substrate 220 , a liquid crystal molecular layer 230 , an upper substrate 240 and a wide viewing angle film 250 . The backlight is a collimated backlight, and the liquid crystal display panel uses a TN display mode. The thickness of the wide viewing angle film is 50 microns, and it is attached to the liquid crystal display panel by ultraviolet light curing. Due to the scattering characteristics of the liquid crystal molecules themselves and the interface scattering characteristics between the liquid crystal and the polymer, the light scattering effect can be improved, thereby increasing the viewing angle of the liquid crystal display of the present invention to achieve the effect of wide viewing angle.

[0046] The wide viewing angle film of the present invention is prepared by the following steps:

Abstract

The invention provides a liquid crystal display. The liquid crystal display comprises a backlight, a liquid crystal display panel and a wide view film; the backlight emits collimated back light and is arranged in rear of the liquid crystal display panel; and the wide view film adopts a light diffusion body and is arranged in front of the liquid crystal display panel. The liquid crystal display has the advantages that the preparation process is simple and easy to realize, the production cost can be greatly saved, industrialization can be realized, and the liquid crystal display has higher light scattering capability than the traditional light scattering film and is uniform for scattering.

Description

technical field [0001] The invention relates to a liquid crystal display, in particular to a liquid crystal display with low cost, simple structure, strong scattering ability and uniform color dispersion and wide viewing angle. Background technique [0002] As a medium, the display device can intuitively express the electrical signal generated by the digital processing unit to the user in the form of graphics, characters, numbers and the like. Display devices can be divided into digital display devices and analog display devices according to their driving methods. LCD (liquid crystal display) is a typical digital display device, and CRT (cathode ray tube) type display device is a typical analog display device. With the development of LCD technology, LCD can realize large screen size and high resolution, and compared with CRT type display devices, it has the advantages of high image quality, small size, light weight, low voltage drive, low power consumption and wide applicati...
