Patent ID: 8823608

Claim:
A display device comprising: a pixel array unit where pixel circuits are disposed in a matrix, said pixel circuit including: a driving transistor configured to generate a driving current, an electro-optic element connected to an output terminal side of aid driving transistor, a storage capacitor for storing a signal corresponding to a signal potential within a picture signal supplied via a picture signal line, a sampling transistor configured to write information corresponding to said signal potential in said storage capacitor, with said electro-optic element emitting light by generating the driving current based on information stored in said storage capacitor at said driving transistor to be applied to said electro-optic element; and a control unit having an output stage that includes a buffer transistor, configured to output a pulse signal for driving said pixel array unit from said buffer transistor; wherein said pixel array unit and said control unit are formed with laser beam irradiation with a predetermined wavelength scanned in the vertical direction or horizontal direction; and wherein the buffer transistor characteristics for each of a plurality of buffer transistors is dependent upon radiation received during at least four separated independent laser radiation application steps, and further wherein a plurality of the buffer transistors include a protruding portion which receives laser radiation.
