Problems solved by technology
However, when the light is transmitted in the upper diffusion sheet 14, part of the light will be absorbed by the upper diffusion sheet 14 and cause part of the light loss; and the use of the upper diffusion sheet 14 will also increase the number of interfaces in the transmission process of the light, thereby increasing the light transmission. Therefore, the use of the upper diffusion sheet 14 will reduce the utilization rate of light, and reduce the display brightness of the liquid crystal display device 100.

Abstract
The invention relates to a prism lens and a method for manufacturing the same. The prism lens consists of a transparent body; the surface of the transparent body is formed with a plurality of strip protrusions; and the height and the width of at least one strip protrusion periodically change along the extending direction. A liquid crystal display device adopting the prism lens has the advantages of having high brightness and avoiding interference of overlapped wave.
Description
technical field [0001] The invention relates to a prism sheet and a manufacturing method thereof. Background technique [0002] See figure 1 , shows a liquid crystal display device 100 using a conventional prism sheet. The liquid crystal display device 100 includes a frame 11 and a plurality of light sources 12 disposed inside the frame 11 , a diffusion plate 13 sequentially disposed above the light sources 12 and covering the frame 11 , a prism sheet 10 and a liquid crystal panel 15 . Wherein, the diffusion plate 13 generally contains scattering particles for diffusing light. like figure 2 As shown, the prism sheet 10 includes a transparent substrate 101 and a lens layer 103 formed on the transparent substrate 101 . The lens layer 103 has a plurality of elongated V-shaped protrusions 105 . Each elongated protrusion 105 extends from one side of the prism sheet to the other side, and a plurality of elongated protrusions 105 are continuously arranged side by side. The l...
