The invention provides a colour filter layer, a colour film substrate comprising the colour filter layer and a display device comprising the colour film substrate, belongs to the display technical field and can solve the problem that light utilization rate of the colour film substrate is low in the prior art. The colour filter layer comprises a filter film and a light conversion material layer arranged at an incident side of the filter film. The colour filter layer is provided with the light conversion material layer, so that lights at other frequencies in incident lights can be converted into lights consistent with spectral properties of each filter film, the effects of increasing light utilization rate and improving display brightness are achieved, energy is effectively saved, and a display effect is effectively improved. |
