Abstract
A method for manufacturing a light guide apparatus includes the following steps. A first mold and a second mold are provided. The first mold and the second mold respectively include a first molding surface and a second molding surface facing each other. A protrusion is disposed at the first or second molding surfaces. Sheet materials are provided. Each sheet material includes an opening corresponding to the protrusion, a first surface and a circuit layer disposed on the first surface. One of the sheet materials is disposed on the first mold with first surface facing the first mold. The first mold and the second mold are closed. An optical plastic material is injected into the space between the first and second molding surfaces to form a light guide plate having a via corresponding to the protrusion for embedding a light source. The sheet material is laminated on the light guide plate.
