<p>A touch input device and a method for manufacturing the same are provided to integrate a touch sense device and a lighting device. A light source(110) generates light. A PCB(Printed Circuit Board)(120) for light guide comprises a transparent substrate body and one or more electrodes. When the generated light is incident on one side, the transparent substrate body propagates the incident light to the inside. At least one electrode is formed on an upper part of the transparent substrate body. A plurality of concave grooves is formed on a lower surface of the transparent substrate body. The concave grooves refract at least a part of the incident light to the electrode.</p> |
