A light guide plate mold ( 100 ) includes a surface ( 103 ) and a plurality of micro structures formed at the surface according to a predetermined pattern. Some micro structures have angular cross-sections and other micro structures have arcuate cross-sections. The light guide plate mold can manufacture light guide plates with simple structures, and the light guide plates can obtain emission light beams with good uniformity and brightness. Therefore, the manufactured light guide plates can be advantageously applied in back light systems of liquid crystal display devices. Furthermore, a method for manufacturing the light guide plate mold is also provided, the method has a relatively low cost, and can be executed with high speed and precision.
