OPTICAL DEVICE AND WEARABLE DISPLAY

摘要

Disclosed are an optical device and a wearable display. A display source is allowed to generate a light beam to display an image. A substrate includes a reflection type diffraction area formed in a mesh structure on one surface. A lens unit makes the light beam incident on one surface of the substrate, wherein the display source produces the light beam. A diffraction area formed on one surface of the substrate collects the light beam incident thereon by diffracting the incident light beam thereon.
