Abstract:
A luminous body mounted in a watch below hands and a protective crystal and controlled by a switch at said watch to produce light, comprising:a first conductive layer, said first conductive layer being transparent, and having a conductor connected to power source;a second conductive layer, said second conductive layer having a conductor connected to power source;an insulative layer sandwiched in between said first conductive layer and said second conductive layer;electroluminescent means arranged on said insulative layer for producing light upon electric connection of electricity to said first conductive layer and said second conductive layer, said electroluminescent means comprising an electroluminescent layer formed of a plurality of electroluminescent indices respectively arranged on said insulative layer around the border area of said insulative layer;a plurality of marks disposed corresponding to the electroluminescent indices of said electroluminescent layer for time indication by the hands of the watch;a light penetrable layer covered on one side of said first conductive layer opposite to said insulative layer and said second conductive layer, said light penetrable layer comprising a plurality of raised portions disposed at locations corresponding the electroluminescent indices of the electroluminescent layer of said electroluminescent means for refracting light.
