PROBLEM TO BE SOLVED : To provide a work display plate usable continuously and cleanly over a long period of time although the work display plate is frequently damaged after used only about three times because the work display plate formed of a metallic material is recessed, bent, distorted, or the like as it is handled in poor environment in the same way as equipment and materials for works. SOLUTION : A plate body 0101 of the work display plate is formed of plastic corrugated cardboard. A recess, a bend or distortion like the metal material is not thereby formed to improve the durability of the work display plate. A reflecting sheet 0102 is disposed on the surface of the plastic corrugated cardboard to improve visibility at night and in a dark place. A re-releasable sheet 0103 is further arranged to allow repeated marking with cut characters, a marker for a white board, or the like. COPYRIGHT : (C)2007, JPO&INPIT
