Method and apparatus for manufacturing display devices

A method for fabricating a display device, which has a plurality of pixels, on a flexible sheet-like substrate transferred in a first direction, said method comprising:

• preparing an imprint roller having a surface with a stumper of partition walls for forming the plurality of pixels and for forming a bus line between electrodes of transistors provided at the plurality of respective pixels and the plurality of pixels, and a stumper of alignment marks being located at a predetermined position with respect to the plurality of pixels;
• forming the partition walls for forming the plurality of pixels and for forming the electrodes of the transistors and the bus line, and forming the alignment marks simultaneously on the flexible substrate along the first direction by pressing the flexible sheet-like substrate against the imprint roller while transferring the flexible sheet-like substrate in the first direction;
• detecting the alignment marks formed on the flexible substrate and obtaining a positional information of the alignment marks;
• a first applying step of, based on the positional information, selectively applying a liquid conductive material between parts of the partition walls for forming the electrodes and the bus line using a first applicator so as to form the electrodes and the bus line;
• and
• a second applying step of, after the first applying step, detecting the alignment marks formed on the flexible sheet-like substrate and, based on positional information of the alignment marks, applying a liquid insulating material or a liquid semiconductor material onto a part of the electrodes or the bus line formed between the partition walls using a second applicator in a selective manner that depends on positions of the transistors.
