Display system having electroluminescent devices

DETAILED DESCRIPTION An improved display system includes a plurality of electroluminescent devices which emit light having an intensity of 0.
5 with a light dispersion angle of 24.
degree.
or less.
An optical device is effective to create a plurality of dispersion patterns from the light emitted by each electroluminescent device.
Each of the dispersion patterns has a viewing angle of 50.
degree.
or more.
The optical device which creates the dispersion patterns may be a light separation panel having an outer side with a first plurality of longitudinally extending side surfaces and a second plurality of longitudinally extending side surfaces which slope transversely to the side surfaces of the first plurality of side surfaces and are interspersed with the first plurality of side surfaces.
The first and second pluralities of side surfaces cooperate to create a plurality of dispersion patterns from the light emitted by the electroluminescent devices.
The dispersion patterns created from the light emitted from any one electroluminescent device are disposed on a line which extends transverse to the side surfaces.
