An illuminated sign is disclosed. By a photoluminescent and marking layer that absorbs light, the illuminated sign stores light energy and emits light spontaneously for making an icon on the f photoluminescent and marking layer visible. The light is generated from a light emitting module that couples to a power supply module for getting power. The photoluminescent and marking layer is disposed on a substrate. Moreover, the device can also emit light by a photoluminescent layer that receives light from the light emitting module and stores the light energy so as to illuminate the icon on a marking layer over the photoluminescent layer.
