PURPOSE: A transparent display apparatus is provided to selectively control transparency and visibility using a blind panel of cholesteric liquid crystal base. CONSTITUTION: An image display unit(10) displays an image using an element consisting of transparent material. A blind panel(20) is combined with the bottom of the image display unit. The blind panel transmits light of visible light band among lights radiated to the blind panel side or reflects the light to the image display side after passing through the image display unit. The blind panel comprises a CLC(Cholesteric Liquid Crystal) which is combined between a first transparent electrode for applying voltage and a transparent electrode more than one layer. |
