A light guide plate (LGP) includes a first surface, a second surface, at least one light incident surface, and a plurality of micro-structure sets. The second surface is opposite to the first surface. The light incident surface connects the first surface to the second surface. The micro-structure sets are separately disposed on the second surface, and the micro-structure sets are not continuous in any direction parallel to the first surface. Each of the micro-structure sets includes at least one protrusive structure that protrudes from the second surface and at least one recessive structure that is recessed in the second surface. A light source module is also provided.
