摘要：
A light guide plate includes at least one surface including a first region having relatively small surface roughness and a second region having relatively great surface roughness, which are adjacently formed. A boundary-blurring pattern composed of a plurality of surface roughness aspects is formed in a boundary part between the first region and the second region.
