1. A see-through type display apparatus comprising:
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, the waveguide comprising a first surface through which the image light is output and a second surface opposite the first surface;
a first lens disposed on the first surface of the waveguide, the first lens having a negative refractive power, and comprising one or more meta lenses; and
a second lens disposed on the second surface of the waveguide, and the second lens having a positive refractive power,
the first lens including a first meta lens disposed on the first surface of the waveguide, the first meta lens having a first refractive power; and
a second meta lens disposed on the first surface and spaced apart from the first meta lens by a first distance, the second meta lens having a second refractive power opposite to the first refractive power.
