    Abstract: A see-through type display apparatus includes an image forming unit; a relay optical system configured to transmit an image provided from the image forming unit and to form a primary imaging image; and an optical combiner configured to reimage the primary imaging image transmitted from the relay optical system and to form a multi-depth plane. The relay optical system includes a lens; a polarizer arranged at an angle with respect to an optical axis and configured to reflect light of light of a first polarization and transmit light of second polarization therethrough; a condensing mirror member configured to reflect and condense light incident from the polarizer; and a polarization converter configured to convert a polarization of light transmitted between the polarizer and the condensing mirror member.
