1. A display device comprising:
a sensor configured to detect a user;
a housing:
a roller accommodated in the housing;
a display configured to be withdrawn from or retracted into the housing by operation of the roller; and
a controller configured to control the roller such that a screen of the display is formed to face at least one of a first direction or a second direction,
wherein the controller is configured to:
control the roller such that a screen output direction matches a direction toward the detected user, when only one user is detected by the sensor, and
determine the screen output direction based on a face of the user located closest to the display among a plurality of users when the plurality of users are detected by the sensor,
determine a withdrawal length of the display based on eye level of the user, control the roller such that the screen output direction matches a direction toward a detected face of the detected closest user and adjust the withdrawal length of the display such that an eye level of the user matches an output position of content displayed on the display.
