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.
