A method of manufacturing a layer containing quantum dots, the layer including first regions where the quantum dots are active and second regions where the quantum dots are inactive, the method including: a) depositing on a support a first layer of a matrix containing quantum dots; b) depositing on the first layer a second resist layer; c) exposing the second layer to light through a mask delimiting the first and second regions, and then developing the resin of the second layer to remove the resin of the second layer opposite the second regions while keeping it opposite the first regions; and d) removing the resin of the second layer opposite the first regions without removing the first layer.

Method of manufacturing a layer containing quantum dots

An optoelectronic device including an array of light-emitting diodes and photoluminescent blocks opposite at least part of the light-emitting diodes, each light-emitting diode having a lateral dimension smaller than 30 &#x3bc;m, each photoluminescent block including semiconductor crystals having an average size smaller than 1 &#x3bc;m, dispersed in a binding matrix.
