A signboard structure includes a case and a face panel detachably connected to a front opening of the case by means of magnetic adherence. The case includes a back panel on which a plurality of light emitting elements are arranged to partially expose from through holes correspondingly provided on the face panel. A watertight and dustproof sealing material is applied into the case to seal joints of the light emitting elements and the back panel to protect the light emitting elements against moistures and dust. Magnetic elements are correspondingly provided on a front side of the back panel and a rear side of the face panel at predetermined positions, so that the face panel can be quickly and detachably assembled to the case to show different static pictures and/or texts painted on the face panel.
