Disclosed is a wearable display apparatus applied to a diffractive optical system. The wearable display apparatus includes: a light source unit which emits color beams of which the wavelength ranges are not overlapped with each other; a light guide part which transmits a beam emitted from the light source unit to the inside by reflection; and a light guide plate which has light exiting parts protruding from one surface of the light guide part and emitting the beam to the outside by regular reflection, and makes the beam emitted from the light guide unit uniformly applied to the surface. A beam emitted from the light guide plate to a panel-type optical modulation element is modulated according to an inputted image signal. The beam emitted from the panel-type optical modulation element is diffracted by a first diffraction element, is coupled with a light guide path and is propagated. The beam transmitted from the light guide path is formed by an image forming element and is enlarged. COPYRIGHT ...
