Abstract
Disclosed is a quantum dot display device including a light emitting unit configured to generate a light; and a color conversion unit configured to convert the light generated from the light emitting unit to a color light. The color conversion unit includes a quantum dot portion configured to convert the light to the color light; a bridge portion configured to provide a color conversion path of the light passing the quantum dot portion and to vertically guide the light; and a prism portion configured to guide the light passing the bridge portion to an outside. The above configuration may enhance the light efficiency by providing a sufficient color conversion path of light.
