Abstract
A color light guide panel, suitable for differentiating an incident light into multiple color lights is provided. The color light guide panel includes a substrate and a color light output structure. The substrate has multiple pixel regions, and the color light output structure is disposed in each of the pixel regions. The color light output structure includes a first nano-pattern, a second nano-pattern and a third nano-pattern. The incident light is scattered by the first nano-pattern for producing a first color light, scattered by the second nano-pattern for producing a second color light, and scattered by the third nano-pattern for producing a third color light. The color light guide panel can output uniform and high luminous first, second and third color light. Moreover, a liquid crystal display device having the above color light output structure is also provided.
