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.
