A sliding advertising board is provided to diversify functions by forming an advertising plane for a fixed image and an advertising plane for images through an advertisement display unit. A sliding advertising board installed on the wall of a building is composed of an advertisement case(100); an advertisement display unit installed in the advertisement case; a beam emitting body(300) emitting a beam from the outside of the advertisement case to the advertisement case; and a controller(400) controlling the advertisement display unit and the beam emitting body. The advertisement display unit is a belt type screen hung and slid by both guide bars installed at the upper and lower sides of the advertisement case, and forms a sign plane(210) printed with an advertisement and an advertising plane(220) to be displayed by the beam emitting body. The controller has a driving unit(120) exchanging the sign plane and the advertising plane by moving a belt through the rotation of the guide bars and a storage medium providing the advertising screen and an image from the beam emitting body, and connects to the network to perform a remote control operation and receive the advertising screen and the image.
