1. A multi-image display apparatus comprising:
an image forming device configured to form an image;
a first polarization plate configured to transmit a first polarization component of the image provided from the image forming device;
a second polarization plate configured to transmit a second polarization component of external light that is provided from a path different from the image, the second polarization component being different from the first polarization component;
a screen configured to reflect and diffuse the image, and transmit the external light;
a polarization selective lens configured to focus the image having the first polarization component, and transmit the external light having the second polarization component without refraction; and
a light guide plate disposed between the screen and the polarization selective lens,
wherein the light guide plate is configured to provide the image coming from the image forming device to the screen through total reflection.
