Abstract
A display device comprising: a light-emissive structure including two regions of light emissive material for emitting light in a viewing direction, the regions being spaced apart in a direction perpendicular to the viewing direction the light-emissive structure being capable of guiding light emitted from one of the light-emissive regions towards the other emissive region; and a barrier structure located between the light-emissive regions for inhibiting the propagation of light guided from the said one of the light-emissive regions to the other light-emissive region.

A display device comprising:
- a light-emissive structure including two regions of light-emissive material for emitting light in a viewing direction, the regions being spaced apart in a direction perpendicular to the viewing direction and the light-emissive structure being capable of guiding light emitted from one of the light-emissive regions towards the other light-emissive region;
- and
- a barrier structure located between the light-emissive regions for inhibiting the propagation of light guided from the said one of the light-emissive regions to the other light-emissive region, wherein the barrier structure is an electrode for injecting electrical charge into the said one of the light-emissive regions.
A display device comprising:
- a light-emissive structure formed on a substrate and including a region of light-emissive material for emitting light in a viewing direction;
- and
- a light-reflective structure formed on the substrate alongside the light-emissive structure for redirecting in the viewing direction light propagating from the light-emissive region to the light-reflective structure, wherein the light-reflective structure is an electrode for injecting electrical charge into the light-emissive material.
