An improved structure of billboard is provided with a transparent layer, an image layer, and a base layer wherein a protective film is disposed on the image layer. The protective film, being through the high-temperature and pressurized process, makes the image layer to be attached to the bottom surface of the transparent layer. Next, the non-transparent and non-reflective base layer is placed on the bottom surface of the image layer to complete the assembly of the billboard. Therefore, just apply an adhesive layer on the bottom surface of the base layer and the billboard can be pasted on the wall or door panel. Owing to non-transparent and non-reflective characteristics, the base layer can effectively prevent shadows from appearing on the image layer to adversely affect the appearance of the image layer due to uneven paste on the adhesive layer or light irradiation on the adhesive layer. |
