发明名称 DISPLAY DEVICE FOR TELEPHONE OR THE LIKE ELECTRIC APPLIANCE
摘要 <p>In a display device employable for telephone or the like electric appliance, a light permeable member constituting an essential component for the display device with information carried thereon includes a first reflective portion at which light beam emitted from a light source is reflected in the light permeable member in the radial direction relative to the optical axis of light beam from the light source and a second reflective portion at which a part of reflected light beam moving in the light permeable member in the direction away from the information is reflected again to be transmitted to the latter. The information on the light permeable member can be clearly recognized by an user with the aid of light beam which has been collected around the information after reflection at the first and second reflective portions.</p>
