Abstract: Disclosed is an AR device which has a thin thickness and a wide FOV and displays an image obtained by mixing a virtual object with the real world. The AR device includes a display unit displaying an augmented image, a reflector reflecting the augmented image displayed by the display unit, and an augmentation unit displaying the augmented image reflected by the reflector along with a real image. The display unit is disposed in an upper boundary of a front viewing angle range of a user, the reflector is disposed at a first angle with respect to the display unit, and the augmentation unit is disposed within the front viewing angle range of the user.

Abstract: A display device capable of actively controlling a viewing angle by an electrical signal, and a method for driving the same, are discussed. The display device in one embodiment includes a first substrate with a plurality of pixels, and a second substrate with convex lens, the second substrate facing the first substrate. Each of the plurality of pixels includes a main pixel and a viewing angle control pixel, and an image is displayed on both the main pixel and the viewing angle control pixel in a wide viewing angle mode. Further, an image is displayed on the main pixel, and a black is displayed on the viewing angle control pixel in a narrow viewing angle mode.
