Abstract
A light guide structure includes a light guide layer, a light condensing structure, and a microstructure region. The light condensing structure is disposed on the light guide layer to gather light from a light source to the light guide layer for allowing the light guide layer to transmit the light. The microstructure region is disposed on the light guide layer to reflect or bend the light transmitted by the light guide layer for allowing the light to be emitted. The light condensing structure and the microstructure region are formed through a co-mold process with the light guide layer together. A keypad structure including the light guide structure and a method of fabricating the light guide structure are also disclosed.
