A multi-primary color display has a backlight source and pixels. Each pixel has at least four sub pixels, which display red primary color, green primary color, blue primary color and a fourth primary color, respectively. At the peak position of the fourth primary color located in the wavelength range between 550 nm˜600 nm, the relative luminance ratio of the fourth primary color to the green primary color is greater than or equal to 0.5. When the ratio of the relative luminance meets the requirement and the relative luminance of a newly added primary color is greater than a certain value, the colors beyond the three-primary color gamut, which includes natural colors and other colors outside the natural color gamut, can be reproduced.
