ABSTRACT:
A method of making an inorganic light-emitting diode display having a plurality of light-emitting elements including providing a substrate, and forming a plurality of patterned electrodes over the substrate. A raised area is formed around each patterned electrode to provide a well before depositing a dispersion containing inorganic, light-emissive core/shell nano-particles into each well. The dispersion is dried to form a light-emitting layer including the inorganic, light-emissive core/shell nano-particles. An unpatterned, common electrode is formed over the light-emitting layer. The light-emitting layer emits light by the recombination of holes and electrons supplied by the electrodes.
