Provided is a method of manufacturing an organic thin film transistor (OTFT). The method comprises forming all components in the OTFT including electrodes, an insulating layer, and an organic layer using laser printing. The laser printing allows formation of a fine pattern by selectively scattering toner only on a portion of a substrate irradiated by a laser beam while eliminating the need for a separate drying process by fixing the toner to the substrate using a fixing roller.

The claimed invention is directed to a flat panel display having R, G, and B unit pixels. At least one of the R, G, and B unit pixels includes at least two or more transistors, each having source and drain regions. At least one drain region in the source/drain regions of at least one transistor in the transistors has a resistance value different from a resistance value of at least a drain region of the other transistor. The difference in resistance values may be accomplished by doping each drain region with a different concentration of dopant or by shaping each drain region differently.
