Abstract
A multi view display comprising a light emitting element having an optical cavity formed by a first and a second reflecting layer, at least said second reflecting layer being semi-transparent, and a light emitting layer arranged between said reflecting layers, wherein said optical cavity is designed so that light emitted in at least two preferred viewing directions has a higher intensity than light emitted in other directions. The invention is based on interference phenomena in the optical cavity, making it possible to realize a light emitting element that intrinsically emits more light in the preferential viewing directions than in other directions. This emission profile makes the light emitting element very useful in a multi view display, reducing the problems of cross talk.
