ABSTRACT:
A laser beam is selectively directed to an amorphous silicon film of a pixel portion on an active-matrix substrate of a display device to modify the amorphous silicon film into a polysilicon film. Pixel circuits such as thin film transistors are formed on the modified polysilicon film. Thus, it is possible to realize remarkably economically the display device provided with the active-matrix substrate having the high performance thin film transistor circuits.
