Abstract
The present invention provides a transparent displaying apparatus, which includes a transparent display (30/40) and a liquid crystal twisting layer (20) arranged on a back surface of the transparent display (30/40). The liquid crystal twisting layer (20) includes therein liquid crystal molecules that selectively exhibit two states of arrangement including a first one of being substantially perpendicular to the transparent display (30/40) and a second one of being substantially parallel to the transparent display (30/40). When the liquid crystal molecules of the liquid crystal twisting layer (20) are arranged perpendicular to the transparent display (30/40), the liquid crystal twisting layer (20) is in a transparent state, such that a viewer may see, on a display screen of the transparent display (30/40), background scenery on the backside of the transparent displaying apparatus; and when the liquid crystal molecules of the liquid crystal twisting layer (20) are arranged parallel to the transparent display (30/40), the liquid crystal twisting layer (20) is in a non-transparent state, such that a viewer does not see, on the display screen of the transparent display (30/40), the backg…
