PURPOSE: A display system for sign board and panel is provided to choose structures of light emitting source in both sides of sign board and panel and facilitate cutting of a board in accordance with a text or a graphic shape. CONSTITUTION: A first diffusion plate(1) and a second diffusion plate(11) are used for providing uniform luminance to an outside plane by diffusing light emitted from a light source. A first insulation plate(2) and a third insulation plate(12) are used as chemical protection plates for preventing a short circuit of a conductive plate, a physical shock, and corrosion of the conductive plate. A second insulation plate(4) is used for securing a spacing between a first conductive plate(3) and a second conductive plate(13) in order to prevent the short circuit. The first conductive plate and the second conductive plate are formed with one body. |
