Abstract:
The display device including pixels has formed therein at least two drive blocks each made up of pixel rows. Each of the pixels includes: a drive transistor; a first capacitor element, a luminescence element; a first switching transistor which causes conduction between the drive transistor and the first capacitor element; and a second switching transistor which applies power supply voltage to the drive transistor. Each of the pixels further includes: a third switching transistor connecting a pixel in a k-th drive block and a first signal line; or a fourth switching transistor connecting a pixel in a (k+1)-th drive block and a second signal line. A first control line for controlling conduction of the first switching transistor and a third control line for establishing a source potential of the drive transistor are connected to each of the pixels in a same one of the drive blocks.
