Abstract
A light source module is provided. At least one light-emitting device emits light and is disposed beside the light guide plate. A light guide plate includes a first surface, a second surface being opposite to the first surface and a light-entering surface connecting the first surface with the second surface. At least one first light guide end, which is located in front of the light-emitting device, and at least one second light guide end, which is connected to the first light guide end, are located on a side of the light guide plate where the light-entering surface is located. A first light-transmitting medium at least located at the first light guide end on the first surface has a refractive index which is larger then a refractive index of a medium or space located at the second light guide end on the first surface. A display device is also provided.
