(Purpose) There is provided with an illumination device for LCD device according to the invention to flow the same electric current through lamps on the same driving voltage, resluting in a long life of said illumination device. (Means of Solution) The device has a light guide plate 10, three or more light sources 11, 12 and 13 provided around at least one of side ends of the light guide plate 10, and a light reflection member 19, surrounding these light sources, to reflect light emitted from the light sources to the light guide plate 10. The light sources 11, 12 and 13 are located so as to have the same parasitic capacitance caused by intervals between the light sources and the light reflection member 19.
