TRANSPARENT DISPLAY APPARATUS

摘要

Disclosed herein is a transparent display apparatus in which a plurality of micro-patterns are formed on a reflection surface of a transparent light guide plate. The transparent display apparatus includes a light source configured to generate light, a transparent light guide plate configured to change a path of the generated light, and to emit the light, a first polarizing plate configured to transmit first polarized light of light emitted from the transparent light guide plate, a liquid crystal panel configured to change a phase of the first polarized light according to driving of liquid crystals; and a second polarizing plate configured to adjust an amount of the first polarized light according to the changed phase of the first polarized light, wherein the transparent light guide plate includes an incident surface to which the light is incident, an exit surface which the incident light exits, a reflection surface being opposite to the exit surface, and a plurality of micro-patterns formed on the reflection surface, and configured to diffuse the incident light.
