Disclosed herein is a multifunctional signboard having a window function. The signboard is constructed so that a film ( 2 ) is provided between double glass sheets ( 3 ) and liquid ( 1 ) is filled between the film ( 2 ) and the glass sheets, thus achieving an effect as if the film ( 2 ) were impregnated with the liquid, and preventing the film ( 2 ) from shimmering due to the refractive indices of the glass sheets and air, therefore serving as a visual device that causes the double glass sheets ( 3 ) and the film ( 2 ) to be perceived as one, and which is constructed so that a transparent film or a film ( 2 ) on which various patterns are printed is wound around take-up rolls ( 4 ) and is driven vertically or horizontally, thus expressing a desired degree of transparency or various designs, therefore variously altering indoor and outdoor environments.
