1. A light source device, comprising:

  • a plurality of light-emitting diodes (LEDs), chromaticities of a part of the LEDs falling in a first area of a chromaticity coordinate diagram, while chromaticities of the other LEDs falling in a second area of the chromaticity coordinate diagram, the second area and the first area being point symmetric to a first white center of the chromaticity coordinate diagram, a chromaticity coordinate value farthest from the white center in the first area being (X1, Y1) and a second chromaticity coordinate value farthest from the white center in the second area being (X2, Y2), wherein 0.06≧

    |X1

    X2|≧

    0.03 and 0.06≧

    |Y1

    Y2|≧

    0.03; and

    a carrier, the LEDs being disposed on the carrier, and a chromaticity difference of any two adjacent LEDs in the chromaticity coordinate diagram being (Δ

    X, Δ

    Y), wherein |Δ

    X|≦

    0.01 and |Δ

    Y|≦

    0.01.
