1. An electroluminescent display device, comprising:
a pixel that includes sub-pixels and having a sub-pixel area where the sub-pixels are disposed and a common area,
wherein each of the sub-pixels includes a light emitting element including an anode electrode and a cathode electrode, and
in the sub-pixel area, a first pixel driving circuit is disposed, and
in the common area, a second pixel driving circuit is disposed, the second pixel driving circuit having a first common line and a second common line; the anode electrode of the light emitting element is electrically connected to the first common line, and
wherein each of the sub-pixels further includes:
a driving element including a source electrically connected to a first node, a gate electrically connected to a second node, and a drain electrically connected to a third node;
a fourth transistor electrically connected to the first node;
a second transistor electrically connected to the second node;
a fifth transistor electrically connected to the third node;
a third transistor electrically connected to the second node and the third node;
a first capacitor having a first electrode electrically connected to the second node and a second electrode electrically connect to the second common line;
a second capacitor having a first capacitor electrode and a second capacitor electrode, the first capacitor electrode electrically connected to the first common line and the second capacitor electrode electrically connected to either the first node or the second node; and
