Abstract: A pixel includes: a light emitting element; a first transistor including a gate electrode electrically connected to a first node, a second node to which a first power voltage for driving the light emitting element is to be applied, and a third node electrically connected to the light emitting element; and a bias control transistor configured to be controlled in operating timing thereof by a bias control signal, and configured to switch electrical connection between the second node and a bias power line for transmitting a bias voltage. In one frame period, a voltage level of the bias voltage to be applied to the second node sequentially increases.

Abstract: A pixel includes: a first transistor including a gate electrode electrically connected to a first node, a second node to which a first power voltage for driving the light emitting element is applied, and a third node electrically connected to the light emitting element; a first emission control transistor having an on-off timing controlled by a first emission control signal; and a second emission control transistor having an on-off timing controlled by a second emission control signal. A time interval exists between a time at which the first emission control signal having a turn-on level is input such that a voltage of the second node is dropped from a bias voltage having a voltage level higher than a voltage level of the first power voltage and a time at which the second emission control signal having a turn-on level is input.
