Abstract
A see-through type display apparatus includes a spatial light modulator configured to time-sequentially output a multi-layered two-dimensional (2D) image, a depth generator configured to generate a multi-layered depth image having pieces of different depth information from the multi-layered 2D image based on a focal distance that is a distance between the depth generator and a focus point of the multi-layered 2D image; and a light path change member configured to change at least one of a first transmission path of light corresponding to the multi-layered depth image and a second transmission path of external light corresponding to an external image, to thereby transmit the multi-layered depth image and the external image to a same area.
