Light guiding sheet and movable contact body using the same |
摘要 |
A concavo-convex light emitting section provided on an under surface of a base material is formed of a synthetic resin with inorganic oxide dispersed therein. A larger amount of light is reflected by inorganic oxide having a large refractive index and dispersed inside the synthetic resin, to cause a plurality of light emitting sections to emit bright light with a small number of light emitting elements. A light guiding sheet capable of making bright and uniform illumination and a movable contact body using the same are realized with a simple configuration. |
