To provide an improved illumination in an illumination display device.
The illumination display device comprises: a dial; a pointer 14; a first light source 36; an optical guide part 27; and an optical filter 24. The optical guide part 27 separates a ray of light emitted from the first light source 36 into first light 58 illuminating the pointer 14 and second light 60 illuminating a front face of the dial. The optical filter 24 has a first filter part 62 that is arranged in an optical path of the first light 58 for transmitting light of a first color, and a second filter part 64 that is arranged in an optical path of the second light 60 for transmitting light of a second color. The optical guide part 27 causes the first light to proceed straight, and causes the second light to proceed from a center of the dial toward a radial direction to irradiate a curved surface of the dial.
