Abstract:
1. A display comprising: a reflective or semi-transmissive display panel; a light-scattering layer disposed on a top surface of the display panel; and an auxiliary light source supplying light to the display panel through the light-scattering layer, wherein the light-scattering layer is an anisotropic front scattering layer which relatively strongly scatters light incident from a specific direction within a first angle range and a second angle range and relatively weakly scatters light incident within an angle range other than the first and second angle ranges, the light-scattering layer has a first scattering central axis corresponding to a first specific angle in the first angle range and a second scattering central axis corresponding to a second specific angle in the second angle range, the first angle range and a third angle range which is an incident-plane symmetrical angle range symmetrical to the second angle range overlap each other in an angle sub-range not including the first specific angle and an incident-plane symmetrical angle symmetrical to the second specific angle, and the auxiliary light source is configured to allow light therefrom incident from a side closer to the auxiliary light source or light therefrom reflected by the display panel to be incident from a side closer to the display panel to mainly enter the light-scattering layer within the second angle range.
