Abstract
An apparatus for manufacturing a light guide in a liquid crystal display and a manufacturing method thereof with a simplified mold structure. In the apparatus, an core material portion is fixed to a light guide molding stamper to constitute a molding device along with the stamper. A fixing member fixes the stamper to the core material portion. The molding device constitutes a mold for molding the light guide, along with a stationary core and a movable core. Accordingly, the stamper and the molding core are integrally formed and sealed, so that a mold structure can be simplified and stable manufacturing of the light guide can be provided.
Claims19
A portion of a mold apparatus for manufacturing a light guide comprising:
- a stamper configured to define a surface of a light guide;
- and
- a core material portion fixed to said stamper by a fixing structure, wherein said fixing structure is an electroplate material plated on said stamper and said core material portion so as to join said stamper and said core material portion.
A method of manufacturing a light guide, comprising:
- defining a molding chamber, including defining at least one surface of the molding chamber with a stamper configured to define a surface of a light guide, wherein the stamper is fixedly mounted on a core material portion with a fixing structure that is an electroplate material plated on said stamper and said core material portion so as to join said stamper and said core material portion;
- and
- molding a molding material in the molding chamber to form a light guide having a surface thereof defined by the stamper.
