A light source includes a substrate and a light-emitting unit. The substrate has a pattern structure, which includes a plurality of concave-convex structures. The light-emitting unit is formed on the pattern structure, and has a backlight surface connected to the pattern structure and a light outputting surface disposed opposite the backlight surface. The pattern structure reflects light, which is outputted from the light-emitting unit in a direction toward the backlight surface, to the light outputting surface.
