Abstract: An LCD including a backlight module and an LCD panel is provided. The LCD panel includes a color light guide panel, suitable for differentiating an incident light into multiple color lights. 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 first˜fourth nano-patterns. 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, scattered by the third nano-pattern for producing a third color light, and scattered by the fourth nano-pattern for producing a fourth color light. The color light guide panel can output uniform and high luminous first˜fourth color light, and the LCD can display high quality image.
