A display device includes a handset having a display window on which an image is displayed, a projection unit included in the handset and enlarging an image and projecting the enlarged image, and a screen movably installed on the handset and displaying the enlarged and projected image thereon. In the display device, an image that the handset displays is displayed on the screen that is larger than the display window of the handset. Thus, various contents such as Internet search or movie can be viewed through an enlarged screen of a mobile handset with more convenience and sense of liveliness. Furthermore, the display device can enlarge an image and project the enlarged image onto a screen for a long time by using a laser scanning method that exhibits a superior optical efficiency and a low power consumption.
