Abstract
A wearable display device according to an embodiment may comprise: a first prism, positioned in front of a user's eye, for controlling the path of an incident light and enabling the arrival of a virtual image to be displayed on the eye; a second prism, coupled to the first prism, for reducing distortion of a real image arriving at the user's eye; and a coating layer which is interposed between the first prism and the second prism and of which the brightness is controlled in inverse proportion to the ambient brightness, such that the visibility of the virtual image increases.
