ABSTRACT:
A display plate preferably employable for an automotive vehicle for the purpose of displaying a certain name or providing a decorative effect is disclosed. The display plate includes a main body to be secured to a vehicle body of the automotive vehicle. A transparent base plate molded of transparent resin material is received in a cavity of the main body. A plurality of half mirrors corresponding to a content to be displayed are formed on the transparent base plate. A prism plate is disposed behind the transparent base plate and a plurality of light reflecting layers each comprising a number of dots or lines are formed on the prism plate. A color filter is interposed between the transparent base plate and the prism plate to scatter light therefrom. To generate light to be emitted from the front surface of the transparent base plate, a lamp is received in a cavity of the prism plate. A light density per unit area on each light reflective layer increases more and more as a distance from the lamp increases.
