Abstract
In the embodiments of the invention, a double-vision backlight module and a LCD device are provided. In the embodiments of the present invention, a light-splitting prism sheet is disposed between a diffuser plate and a LCD panel for splitting light. The prism sheet is arranged such that a side having prisms thereon of the prism sheet faces the LCD panel, and thereby splitting the light and enhancing the brightness, and eventually enhancing the brightness in both left and right view areas and at the same time reducing the brightness in the central-interference area, and thus improving the double-vision effect.
