TFT, flat panel display device having the same, method of manufacturing TFT, method of manufacturing flat panel display device, and method of manufacturing donor sheet

A method of manufacturing a thin film transistor, comprising:

• partitioning a plurality of nanoparticle lines;
• forming nanolayers on the nanoparticle lines, each nanoparticle line comprising a nanoparticle;
• and
• forming an active layer by patterning the nanolayers.

A method of manufacturing a flat panel display device, comprising:

• providing the flat panel display device comprising an emission region comprising a plurality of pixels and a selection driving circuit comprising a thin film transistor comprising a semiconductor active layer arranged in each of the pixels;
• partitioning a plurality of nanoparticle lines;
• forming nanolayers on one of said nanoparticle lines, each nanoparticle line comprising a nanoparticle;
• and
• forming an active layer by patterning the nanolayers.

A method of manufacturing a donor sheet, the method comprising:

• preparing a film having one side formed of a light-to-heat conversion layer;
• preparing a water bank comprising a solution comprising one of P-type nanoparticles and N-type nanoparticles;
• collecting the nanoparticles to one side;
• allowing the film to travel through the solution in the water bank so that the nanoparticles become attached to the light-to-heat conversion layer of the film;
• and
• drying the film.
