A display device includes a visible light reflecting layer and a fluorescent layer. The visible light reflecting layer transmits an invisible light. The visible light is reflected from the visible light reflecting layer. The fluorescent layer is on the visible light reflecting layer to generate a visible light in response to the invisible light that has passed through the visible light reflecting layer. The fluorescent layer transmits the visible light reflected from the visible light reflecting layer. Therefore, a manufacturing cost is decreased, and an efficiency of light is improved.
