Abstract: An optical system is provided which includes a light source which outputs light; a first waveguide; a transmissive reflective layer provided on a top surface of the first waveguide and configured to reflect some light and transmit the remaining light incident thereon; a second waveguide provided on a top surface of the transmissive reflective layer; an in-coupler provided on the first waveguide and configured to allow the light output by the light source to enter the first waveguide; and an out-coupler provided on one of the first waveguide and the second waveguide and configured to emit light from the optical system.

Abstract: Provided are a wearable display device and a light guide element thereof, the display device including: a display element configured to project a first light forming a virtual image; and a light guide element configured to guide the first light from the display element and a second light input from outside of the wearable display device to a predetermined position. The light guide element includes: a first optical surface facing the display element; a second optical surface and a third optical surface configured to reflect the first light input through the first optical surface; and a fourth optical surface configured to reflect the reflected first light to the predetermined position. The first to third optical surfaces are flat surfaces, and the fourth optical surface is a rotationally asymmetric reflective surface.
