Patent ID: 8305308

Claim:
A display device including pixels arranged in rows and columns, the display device comprising: a first signal line and a second signal line that are disposed in each of the columns, for supplying the pixels in the corresponding column with a signal voltage that determines luminance of the pixels; a first power source line and a second power source line; a scanning line disposed in each of the rows; and a control line disposed in each of the rows, wherein the pixels compose at least two drive blocks each of which includes at least two of the rows, each of the pixels includes: a luminescence element that includes terminals, one of the terminals being connected to the second power source line, and the luminescence element generating photons according to a flow of a signal current corresponding to the signal voltage; a drive transistor that includes a gate, a source, and a drain, one of the source and the drain being connected to the first power source line, the other of the source and the drain being connected to the other of the terminals of the luminescence element, and the drive transistor converting the signal voltage applied between the gate and the source of the drive transistor into the signal current; a capacitor element that includes terminals, one of the terminals being connected to the gate of the drive transistor; a first switching transistor that includes a gate connected to the scanning line, one of a source and a drain connected to the one of the terminals of the capacitor element, and the other of the source and the drain connected to a fixed potential line; and a second switching transistor that includes a gate connected to the control line, one of a source and a drain connected to the other of the terminals of the capacitor element, and the other of the source and the drain connected to the source of the drive transistor, each of the pixels in a k-th drive block of the drive blocks further includes a third switching transistor that includes a gate connected to the scanning line, one of a source and drain connected to the other of the terminals of the capacitor element, and the other of the source and the drain connected to the first signal line, k being a positive integer, and each of the pixels in a (k+1)-th drive block of the drive blocks further includes a fourth switching transistor that includes a gate connected to the scanning line, one of a source and a drain connected to the other of the terminals of the capacitor element, and the other of the source and the drain connected to the second signal line.
