Abstract
A display device includes a light-emitting element; a capacitor connected to and disposed between a first node and a second node; a first transistor including a first electrode connected to a reference voltage supply line and a second electrode connected to the first node, and supplying a reference voltage to the first node in response to a light-emission control signal of an n-th pixel row; a second transistor including a first electrode connected to the reference voltage supply line and a second electrode connected to the second node, and supplying the reference voltage to the second node in response to a first scan signal of an (n−1)-th pixel row; and a driving transistor including a gate electrode connected to the second node, a first electrode receiving a high-potential driving voltage, and a second electrode connected to a third node. Thus, for example, occurrence of a reference voltage related short-circuit in the light-emitting element of the display device is suppressed to prevent occurrence of defective image display in each pixel and to improve reliability thereof.
