Abstract
A display that includes an image producing system and a light filtering layer in the blue range, the light filtering layer having a limited impact on the gamut of the display. The image producing system has a gamut Gdefined in a color space The light filtering layer includes semi-conductive nanoparticles, and the absorbance through the light filtering layer is greater than 0.25 for each light wavelength ranging from 350 nm to λ, λbeing in the range from 420 nm to 450 nm. The gamut Gof the image producing system with the filtering layer has an area greater than 90% of the area of gamut Gin the color space.
