1. An electroluminescent display device, comprising:
a plurality of pixels; and
a common circuit connected to the plurality of pixels, wherein each 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 and the second node, the fourth node of the pixel electrically connected to a fourth node of at least one other pixel from the plurality of pixels;
a second transistor connected to the first node and a data line;
a light emitting element electrically connected to the driving transistor; and
a bias voltage control transistor that determines whether to apply a bias voltage to the first node,
wherein the common circuit is electrically connected to the fourth node included in each of the plurality of pixels and includes:
a high-potential voltage providing circuit configured to provide a high-potential voltage to the fourth node in each of the plurality of pixels; and
a reference voltage providing circuit configured to provide a reference voltage to the fourth node in each of the plurality of pixels.
