PURPOSE: A sand-blasting light guide plate manufacturing method is provided to prevent processing errors or damage on the surface of a light guide plate. CONSTITUTION: A non-punched metal stencil is prepared(S100). A desired micro-pattern is punched on the metal stencil(S110). The metal stencil is placed and closely adhered on a transparent panel(S120). An etching process is performed using a send-blasting apparatus(S130). The magnetic force of a magnetic base is switched off when a send-blasting process is ended. The metal stencil is separated from the transparent panel(S140).
