A display comprising: a backlight; a plurality of layers placed above the backlight, the plurality of layers including: a first controllable absorption layer (12,22,32) capable of controlling the absorption of light in a first wavelength band of a plurality of wavelength bands while being substantially transparent to light in other wavelength bands of the plurality of wavelength bands; a first luminescent layer (14,24,34) placed between the backlight and the first controllable absorption layer (12,22,32) and capable, in response to light from the backlight, of emitting light within the first wavelength band; at least one reflective layer (15,25,35) placed between the backlight and the first luminescent layer (14,24,34) and adapted to reflect light in at least the first wavelength band; a second controllable absorption layer (12,22,32) capable of controlling the absorption of light in a second wavelength band of the plurality of wavelength bands while being substantially transparent to light in other wavelength bands of the plurality of wavelength bands; a second luminescent layer (14,24,34) placed between the backlight and the second controllable absorption layer (12,22,32) and capable, in response to light from the backlight, of emitting light within the second wavelength band; and a second reflective layer (15, 25, 35) placed between the backlight and the second luminescent layer (14,24,34) and adapted to reflect light in at least the second wavelength band; wherein the first and the second reflective layers may optionally form together one single reflective layer adapted to reflect light within at least the first and the second wavelength bands and which is placed between the backlight and both of the first and the second luminescent layers. a backlight;
