A display device for providing user interaction, the device comprising: a display body; a display panel disposed in the display body and configured to display video images; a photographing unit including a camera module for detecting a user's gesture; and a driving unit for selectively moving the photographing unit to a selected position from among a first position where the photographing unit is received in an upper part of a rear of the display panel, and a second position and a third position where the photographing unit projects outward from the display body, during photographing, wherein in the second position an end portion of the photographing unit is at a furthermost position from the display body, and in the third position the end portion of the photographing unit is closer to the display body than in the second position. wherein the driving unit comprises: a slider being hinge-engaged with the photographing unit; a locking member being included in the slider to fix a position of the slider such that the photographing unit is kept fixed at the first position; an elastic member for elastically supporting the slider such that the photographing unit moves from the first position to the second position when the locking member is unlocked; and a speed reducing member for, in response to the photographing unit moving from the first position to the second position, reducing a moving speed of the slider and keeping the photographing unit at a predetermined angle in a section between the second position and the third position, wherein the speed reducing member is a rotary damper being gear-engaged with the slider, and for keeping the photographing unit fixed at a certain point in the section between the second position and the third position, and wherein the slider comprises: an engagement unit being gear-engaged with the rotary damper when the photographing unit is in the section between the first position and the second position; and an extension unit being gear-engaged with the rotary damper when the photographing unit is in the section between the second position and the third position. a display body; a display panel disposed in the display body and configured to display video images;
