Abstract
A display panel includes: first to N-th active pixels, N being an integer greater than 3; and a dummy pixel arranged adjacent to the N-th active pixel in a same pixel column, the dummy pixel including: a dummy driving transistor including a gate electrode connected to a first node, a first electrode connected to a data line configured to transmit a data voltage, and a second electrode connected to a second node; a plurality of dummy compensation transistors connected in parallel to each other between the first node and the second node; a dummy initialization transistor including a gate electrode configured to receive an initialization gate signal, a first electrode configured to receive an initialization voltage, and a second electrode connected to the first node; and a dummy storage capacitor including a first electrode configured to receive a first supply voltage and a second electrode connected to the first node.
