A pixel circuit comprising:

• a first transistor including a first terminal connected to a first node, a gate terminal connected to a second node, and a second terminal connected to a third node;
• a second transistor including a first terminal connected to a data line, a second terminal connected to the first node, and a gate terminal that receives a first gate signal;
• a third transistor including a first terminal connected to the third node, a second terminal connected to the second node, and a gate terminal that receives a second gate signal;
• a fourth transistor including a first terminal connected to the second node, a second terminal that receives a first initialization voltage, and a gate terminal that receives an initialization control signal;
• an emission transistor connected to either the first node or the third node and including a gate terminal that receives an emission control signal;
• a seventh transistor including a first terminal connected to the fourth node, a second terminal that receives a second initialization voltage, and a gate terminal that receives a bias control signal;
• an eighth transistor including a first terminal connected to the first node, a second terminal that receives a bias voltage, and a gate terminal that receives the bias control signal;
