Abstract: A light source module includes a light guide plate, at least one light emitting element, a circuit board, and a heat conductive structure. The light guide plate has a light incident surface and a bottom surface adjacent to each other. The light emitting element is disposed beside the light incident surface. The circuit board has a bottom and a sidewall. The bottom extends toward the light guide plate from an end of the sidewall. The sidewall has a first surface facing the light incident surface, and the bottom has a second surface facing the bottom surface. The light emitting element is disposed on the first surface. The heat conductive structure is disposed on the circuit board contacted the first surface and the second surface of the circuit board, for transmitting heat generated by the light emitting element and the circuit board.
