Abstract: The display device has a microdisplay, a mirror, and a three-dimensional renderer. The microdisplay has a display surface. A width of the display surface is narrower than a pupil distance between user's right and left pupils. The microdisplay is disposed so that a center of the display surface is equally distant from the right and the left pupils, and the display surface is directed toward a line of sight of the user. The mirror is located at a position at which the display image displayed on the display surface has one-time reflection so that the user views the virtual image symmetrically curved. The three-dimensional renderer processes an input signal and generates the display image to be displayed on the display surface so that when the user views the virtual image, the user accepts the virtual image as if the virtual image is displayed on a three-dimensional surface surrounding the user.
