1. A light source module, comprising a substrate, at least one light-emitting element, an optical adhesive layer and a reflective structure, wherein:
the at least one light-emitting element is disposed on the substrate and configured to provide a light;
the optical adhesive layer is disposed on the substrate and covers the at least one light-emitting element, and comprises a first surface and a second surface opposite to each other, the first surface faces the substrate, and the second surface is away from the substrate; and
the reflective structure is disposed in the optical adhesive layer and located above the at least one light-emitting element, a part of light emitted from the at least one light-emitting element toward the reflective structure directly passes through the reflective structure, and the other part of the light is reflected by the reflective structure, wherein a width of the reflective structure is greater than or equal to a width of the at least one light-emitting element, and a thickness of the reflective structure is greatest at its center, and a thickness outside the center is less than the thickness at the center,
wherein the light source module further comprises a reflective layer disposed on the substrate.
