An electronic color-chart device includes plural LEDs with different peak wavelengths and displays images to serve as color references as color charts by making the plural LEDs emit light. In a case where a light emission intensity distribution of each of the plural LEDs is normalized with a maximum intensity being a value of 1, the plural LEDs include plural first LEDs of which at least one is an LED whose full wavelength width at half maximum intensity is 40 nm or narrower and between which a peak interval is 50 nm or narrower and a second LED whose light emission intensity at a wavelength of 555 nm is 0.4 or higher, and whose full wavelength width at half maximum intensity is wider than 40 nm.
