Description

【Technical field】

[0001] The invention relates to a prism sheet applied to a liquid crystal display device and a backlight module using the prism sheet. 【Background technique】

[0002] In recent years, liquid crystal displays have been widely used due to their lightness, thinness, small size and low power consumption. Since the liquid crystal display panel itself does not have light-emitting characteristics, a backlight module is required to provide a backlight for it to realize the display function of the liquid crystal display panel.

[0003] Please refer to FIG. 1 , which is an exploded view of a prior art backlight module. The backlight module 10 includes a prism sheet 11 , a light source 12 , a reflection plate 13 and a light guide plate 14 . The prism sheet 11 includes a base body 110, one surface of the base body 110 is a light incident surface 113 for receiving light beams, and the light incident surface 113 is provided with a plurality of V-shaped grooves 1131 par...
