<p>PURPOSE: An optical touch panel and a method for manufacturing the same are provided to integrate a lens with an over-clad layer, thereby providing excellent optical transmission efficiency and shock resistance. CONSTITUTION: A light emitting end of an LGP(Light Guide Plate)(14) of a receiving side and a light incident end of an LGP of an emitting side face with a coordinate input area(11) between them. The LGPs of the light emitting and incident sides include under clad layers(16a,16b), cores(17a,17b) on the under clad layers and over clad layers(18a,18b) covering the core and under clad layers. The under clad layers and over clad layers have lower refractive indexes than the core.</p> |
