a rollable display panel configured to display an image;
a display drum configured to rotate so that the rollable display panel is rolled or unrolled;
a housing provided with the display drum rotatably installed therein, and comprising a display drawing-out slot through which the rollable display panel passes when the rollable display panel is rolled or unrolled; and
a self-standing guide unit configured to guide the rollable display panel to be curved in an arc shape so that the rollable display panel stands upright on its own when the rollable display panel is unrolled from the display drum and drawn out of the housing,
wherein the self-standing guide unit is installed between the display drum and the display drawing-out slot to guide the rollable display panel, and
wherein the self-standing guide unit comprises:
a first guide roller rotatably installed between the display drum and the display drawing-out slot; and
a second guide roller configured to rotate in a state of being spaced apart from the first guide roller so that a guide slot through which the rollable display panel passes is formed between the first guide roller and the second guide roller, and
wherein the guide slot has a curved shape in a horizontal direction, so as to allow the rollable display panel to be curved in the arc shape when the rollable display panel passes therethrough.
