A light source device including light-emitting diodes (LEDs) and a carrier is provided. Chromaticities of some LEDs fall in a first area of a chromaticity coordinate diagram, while chromaticities of the other LEDs fall in a second area of the chromaticity coordinate diagram. The second area and the first area are point symmetric to a white center of the chromaticity coordinate diagram. A chromaticity coordinate value farthest from the white center in the first area is (X1, Y1), and a chromaticity coordinate value farthest from the white center in the second area is (X2, Y2), wherein 0.06≧|X1−X2|≧0.03 and 0.06≧|Y1−Y2|≧0.03. The LEDs are disposed on the carrier, and a chromaticity difference of any two adjacent LEDs in the chromaticity coordinate diagram is (&Dgr;X, &Dgr;Y), wherein |&Dgr;X|≦̸0.01 and |&Dgr;Y|≦̸0.01.
