An electric signboard used as an advertising plate is provided to reduce the weight of products and the manufacturing time and cost by fixing a PCB(Printed Circuit Board) through a guide grove of a case and to increase resolution by adding an LED(Light Emitting Diode) to a space where a bolt combining tool is formed. An electric signboard used as an advertising plate is composed of a PCB(22); light emitting pixels(24) aligned on the PCB; a case(21) for protecting the PCB and the light emitting pixels; and an upper board(25) for an advertisement attached to or detached from the front side of the case. The light emitting pixels are formed by a unit of at least one line on the PCB. The case includes a guide groove(23) for guiding the PCB to the inside. |
