Abstract:
1. A multi view display comprising a light emitting element, comprising: an optical cavity formed by: a light emitting layer arranged between said reflecting layers, said optical cavity being configured so that a resonance of light emitted by the light emitting layer causes said light to be emitted in at least two preferred viewing directions through the second reflecting layer, the at least two preferred viewing directions being at an oblique viewing angle on both sides of an axis normal to the optical cavity, wherein the light in the two preferred viewing directions has a higher intensity than light emitted in other directions, wherein an optical distance, d, between the first and second reflective layers is chosen so that a wavelength corresponding to a resonance maximum at the viewing angle is near a dominant wavelength λ where λ is the wavelength of the emitted light, and a width of the emitted light in the viewing direction is determined based on a product of the reflective coefficients of the reflecting layers (/r
