The present invention provides a light source device, which includes a light source and a light guide plate. The light source is used to provide multiple light beams. The light guide plate is used to guide the multiple light beams and includes multiple microstructures. The light guide plate has a light incident surface and a first surface. The light incident surface is connected to the first surface. The light source is arranged on one side of the light incident surface. Multiple microstructures are arranged on the first surface. Each of the multiple microstructures has a light-facing surface facing the light source. Each of the multiple microstructures satisfies the following condition: θ'=arctan((Δx‑sin(arctan(x / Δy))*a) / Δy). The light source device of the present invention can produce a more accurate pattern.
