Embodiment Construction

[0021] In order to have a further understanding and understanding of the features, purposes and functions of the present invention, the relevant detailed structure and design concept of the device of the present invention will be explained, so that the characteristics of the present invention can be understood, and the detailed description is as follows

[0022] see Figure 3A As shown, this figure is a schematic diagram of a preferred embodiment of a polarizing plate of the present invention. The polarizer 3 includes a light selective reflective film 31 and a birefringent film 32 . The birefringence film 32 is formed on the light selective reflection film 31 . The light selective reflective film 31 is a liquid crystal material having a helical shape. The value of Nz=(nx−nz) / (nx−ny) of the birefringence film 32 is between −0.1 to −5.0. The birefringent film can absorb light in a certain wavelength range, and in this embodiment, the wavelength range is the wavelength range o...

Abstract

The invention relates to a polarized light board that includes a light selection reflection film and a double reflection film. The double reflection film is formed on the light selection reflection film. And the Nz=(nx-nz) / (nx-ny) value of double refection film could be in -0.1í¬5.0, nx is the slow axis refraction coefficient of the double refection film, and ny is the fast axis refraction coefficient, and nz is the refraction coefficient along thickness direction. The refraction film could be formed by one from polycarbonate, cellulose triacetated, metallocene cyclomonoolefin copolymer and macromolecule expanding foam material. The invention could solve the problem of red deflection phenomenon when watching in large visual angle of liquid crystal display.

Description

technical field [0001] The invention relates to a polarizing plate, in particular to a polarizing plate formed by combining a light selective reflective film and a birefringent film. Background technique [0002] The traditional liquid crystal display uses two crossed polarizers to produce light and dark changes. When the non-polarized light generated by the backlight of the liquid crystal display passes through the rear polarizer installed on the liquid crystal panel, more than half of the light source will be absorbed, making Light utilization efficiency becomes poor. [0003] In order to solve this problem, a polarizing plate technology with circular dichroism (circular dichroism) has been produced, such as U.S.Pat.No. Polarizer technology with circular dichroism. see figure 1 As shown, this figure is a schematic diagram of the action of the polarizer with circular polarization dichroism in the prior art liquid crystal display. The liquid crystal display 9 is sequenti...
