A display panel for optical signs (100) comprises a transparent base member (108) with the information grooves (106) on it. Furthermore, a transparent color glue material is filled into the information grooves to form an information layer (110), which presents a three-dimension visible effect. In order to improve the visible effect and enhance the light intensity of the information to be presented, the transparent base member (108) is coated on its one surface with a reflective layer before an opaque layer is applied. A light source (120) is positioned on a surface opposite to that of coatings and a housing encloses the light so that the surface of transparent color glue layer is a face of the housing.
