Abstract
A display includes: 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. 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. The light-scattering layer has a first scattering central axis and a second scattering central axis. The first angle range and a third angle range overlap each other in an angle sub-range not including a first specific angle and an incident-plane symmetrical angle symmetrical to a second specific angle. The auxiliary light source allows light therefrom incident from a side closer to the auxiliary light source or from a side closer to the display panel to mainly enter the light-scattering layer within the second angle range.
