Description

technical field

[0001] The present invention relates to display devices, and in particular to display devices comprising organic electroluminescent elements. Background technique

[0002] Organic electroluminescence (EL) elements emit light when an electric current is applied to a thin organic layer between two electrodes. Such organic EL elements are two-dimensionally arranged to constitute a display device.

[0003] There is a problem that the light extraction efficiency of the organic EL element is low. Although light is emitted at various angles from the thin light-emitting layer, total reflection occurs at the boundary surface between a layer sandwiching the light-emitting layer (such as a protective layer) and an external space, so that light is confined within the light-emitting element and most of the light is blocked. Light is extracted into the outer space. In order to solve this problem, various solutions have been proposed.
