一种光源模块，其包括导光板、光源与胶体。导光板具有耦光区与出光区，其包括入光面、第一面、第二面、多个第一微结构以及多个第二微结构。耦光区位于入光面与出光区之间。入光面连接第一面与第二面。第二面相对于第一面。这些第一微结构设置于出光区且凸起于第一面。这些第二微结构设置于耦光区且凸起于第一面与第二面其中至少一者，其中这些第一微结构的形状不同于这些第二微结构的形状。光源设置于入光面旁。胶体设置于光源与入光面之间。一种显示设备亦被提出。

A light source module including a light guide plate, a light source and an adhesive material is provided. The light guide plate having a light-coupling region and a light-emitting region includes a light-incident surface, a first surface, a second surface, a plurality of first microstructures and a plurality of second microstructures. The light-coupling region is located between the light-incident surface and the light-emitting region. The light-incident surface is connected to the light-incident surface and the bottom surface. The second surface is opposite to the first surface. These first microstructures are disposed to the light-emitting region and protrude from the first surface. These second microstructures are disposed to the light-coupling region and protrude from at least one of the first surface and the second surface, wherein the shape of these first microstructures is different from the shape of these second microstructures. The light source is disposed adjacent to the light-incident surface. The adhesive material is disposed between the light source and the light-incident surface. A display device is also provided.
