Patent attributes
The present invention discloses a high-speed flat panel display with a long lifetime, wherein thin film transistors in a pixel array portion in which a plurality of pixels are arranged and a driving circuit portion for driving the pixels of the pixel array portion, have different resistance values than each other or have different geometric structures than each other. The flat panel display comprises a pixel array portion where a plurality of pixels are arranged, and a driving circuit portion for driving the pixels of the pixel array portion. The thin film transistors in the pixel array portion and the driving circuit portion have different resistance values in their gate regions or drain regions than each other, or have different geometric structures than each other. One of the thin film transistors in the pixel array portion and the thin film transistors in the driving circuit has zigzag shape in its gate region or drain region or has an offset region.
