摘要： A light source device includes a light guide plate, an optical adhesive, and a light source element. The light guide plate includes a light guide substrate and an enhancement layer. The light guide substrate has a light incident surface, a first surface, and a second surface. The first surface is opposite to the second surface, and the light incident surface extends between the first surface and the second surface. The enhancement layer is disposed on the light guide substrate. A thickness of the enhancement layer is from 1 micrometer to 25 micrometers and a first refractive index of the light guide substrate is greater than a second refractive index of the enhancement layer. The optical adhesive is interposed between the first surface of the light guide substrate and the optical adhesive. The light source element is disposed beside the light incident surface to emit light toward the light incident surface.
