Display panel and electroluminescent display device including the same and pixel driving circuit

Abstract

The disclosure provides a display panel configured to enhance image quality and an electroluminescent display device including the same, and a pixel driving circuit. An electroluminescent display device according to an embodiment of the disclosure comprises a plurality of pixels including at least two pixels and a common circuit disposed between the plurality of pixels. One of the plurality of pixels includes a driving transistor including a first node, a second node, and a third node, a capacitor connected to a fourth node electrically shared by the plurality of pixels and the second node, a second transistor connected with the first node and a data line, and a light emitting element electrically connected with the driving transistor. The common circuit includes a high-potential voltage providing circuit providing a high-potential voltage to the fourth node and a reference voltage providing circuit providing a reference voltage.
