Patent ID: 8169432

Claim:
An electronic apparatus including a main body part and a display part that displays information output from the main body part, the display part comprising: a pixel array part configured to include scan lines disposed along rows, signal lines disposed along columns, and pixels that are disposed at intersections of the scan lines and the signal lines and are arranged in a matrix; and a drive part configured to drive the pixel array part and include a control scanner and a signal selector, the control scanner sequentially applying a control pulse to the scan lines with a predetermined horizontal cycle to thereby line-sequentially scan the pixels on a row-by-row basis, the signal selector supplying a video signal to the signal lines disposed along the columns in matching with the line-sequential scanning, wherein the pixel includes a sampling transistor having a gate connected to the scan line and a source and a drain one of which is connected to the signal line, a drive transistor having a gate connected to the other of the source and the drain of the sampling transistor and a source and a drain one of which is connected to a power supply, a light-emitting element connected to the other of the source and the drain of the drive transistor, and a hold capacitor connected between the source and the gate of the drive transistor, the sampling transistor is kept at an on-state during a period from rising of a control pulse supplied from the control scanner to falling of the control pulse with a time width shorter than one horizontal cycle, and samples a video signal from the signal line to write the video signal to the hold capacitor, the sampling transistor has a double gate structure in which a pair of transistor elements are connected in series between the signal line and the gate of the drive transistor and gates of the pair of transistor elements are connected in common, and the drive transistor causes a drive current dependent on a video signal written to the hold capacitor to flow to the light-emitting element for light emission.
