Methods for manufacturing a display device

A method for manufacturing a display device comprising:

• providing a thin film transistor (TFT) substrate having a plurality of sub-pixel locations and a plurality of TFTs;
• providing a carrier substrate supporting a plurality of light emitting diodes (LEDs), wherein each of the plurality of LEDs has a first electrical contact and a second electrical contact;
• transferring the plurality of LEDs from the carrier substrate to the TFT substrate, with a corresponding one of the plurality of LEDs being disposed at each of the plurality of sub-pixel locations;
• fixing positions of the plurality of LEDs with respect to the TFT substrate;
• providing a filling insulator contacting sidewalls of the plurality of LEDs;
• determining that a first LED of the plurality of LEDs is defective;
• and
• electrically isolating the first electrical contact of the first LED determined to be defective, wherein electrically isolating the first electrical contact comprises laser cutting a first electrode of the display device.
