Abstract
See-through type display apparatuses and electronic apparatuses including the same are disclosed. A see-through type display apparatus may include a multipath optical member that transfers a plurality of images along a plurality of paths to an ocular organ of a user, and an anisotropic optical member that is arranged between the multipath optical member and the ocular organ of the user. The anisotropic optical member may exhibit characteristics which vary based on a polarization direction of incident light. For example, the anisotropic optical member may function as a lens with respect to light that propagates along a first path and function in a different manner than the lens with respect to light that propagates along a second path. The anisotropic optical member may function as a flat plate with respect to the light that propagates along the second path.
