Abstract
A see-through type display apparatus includes an image projector configured to output image light, a waveguide configured to receive the image light output from the image projector and transmit the image light to a user's view, and a first lens having a negative refractive power and a second lens having a positive refractive power, which are arranged on both surfaces of the waveguide. Each of the first lens and the second lens includes one or more meta lenses and is configured to operate as a lens with almost no chromatic aberration, thereby implementing a thin optical system having good image quality.
