Abstract
A display including a driving substrate is provided. Arrayed on the driving substrate is a plurality of pixel electrodes and thin film transistors for driving the pixel electrodes. Each thin film transistor includes a semiconductor thin film having an active region made to be polycrystalline by irradiation with an energy beam, and a gate electrode provided so as to cross the active region. In a channel part of the active region overlapping with the gate electrode, the crystal state is varied periodically along the channel length direction, and substantially the same crystal state crosses the channel part.
