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.
