Patent ID: 7727788

Claim:
A method of manufacturing a display device, the method comprising: preparing a porous template by forming an array of pores having predetermined sizes in the porous template; stacking impurity-doped compound semiconductor layers inside corresponding ones of the pores in the porous template and sintering the semiconductor layers to form a plurality of light emitting diode (LED) chips within the porous template, with the compound semiconductor layers being formed of quantum dots by injecting nano particles or nano particle precursors into the pores together with impurities; hydrophilically treating surfaces of the porous template exposing ends of the LED chips; releasing the LED chips from the pores in the porous template by removing the porous template with an etchant; forming a plurality of first electrodes on a substrate; attaching the LED chips to pixel sites on the first electrodes during fluidic self assembly (FSA); and forming a plurality of second electrodes on top surfaces of the LED chips.
