PROBLEM TO BE SOLVED: To provide variable display structure capable of switching the display and adding changes in the appearance, while suppressing cost. SOLUTION: The variable display structure is provided with a first light source 3 and a second light source 4 where the wavelength of light beams to be outputted are mutually different; a second printing part 10a for reflecting only the wavelength of light from the first light source 3; a second printing part 10b for reflecting only the wavelength of light from the second light source 4; a background-printing part 10d which does not reflect the wavelengths of light beams from both the first and the second light sources 3, 4; and a dimming printing part 10c, capable of adjusting luminance and hue by suppressing light beams from the first and the second light sources 3, 4 and reflecting the waveforms of light beams from both the first and the second light sources 3, 4.
