A double-sided advertisement panel using a light guide plate is provided to emit the light of a light emitting plate through both sides of the light guide plate after dispersing the light through a reflective sheet and to reflect the light over the whole surface at uniform luminance by a reflection pattern. A double-sided advertisement panel(10) using a light guide plate(20) is composed of a light emitting plate(50) made of soft materials and equipped with plural light sources(52); a reflective sheet for reflecting the light emitted from the light emitting plate; and the light guide plate in which the reflective sheet is embedded. The light emitting plate is installed at an edge of the light guide plate. The light source is an LED(Light Emitting Diode) or a cold cathode-ray lamp. |
