Abstract
A display device includes a display element emitting a light by a current flowing, a drive transistor configured to control the current flowing through the display element, and a plurality of diode connection transistors connected in series to a source side of the drive transistor, and a source of any on the drive transistor or the plurality of diode connection transistors is connected to a back gate of the drive transistor.
Claims8
A display device comprising:
- an organic Electro Luminescence (EL) element emitting light when the organic EL element is powered by an electrical current;
- a drive transistor configured to control the electrical current flowing through the organic EL element;
- and
- a plurality of diode connection transistors connected in series to a source side of the drive transistor,
- wherein a source of both of the drive transistor and the plurality of diode connection transistors is connected to a back gate of the drive transistor, and
- the plurality of diode connection transistors is provided between the source side of the drive transistor and the organic EL element and is connected in series to both of the drive transistor and the organic EL element.
