Abstract: A display panel and an electronic device including the same are disclosed. A circuit layer of the display panel includes at least a first transistor and a second transistor. The first transistor includes a first oxide semiconductor pattern, a gate electrode, a first electrode in contact with one side of the first oxide semiconductor pattern, a second electrode in contact with the other side of the first oxide semiconductor pattern, and a first-first metal pattern disposed on the substrate to overlap the first oxide semiconductor pattern. The second transistor includes a second oxide semiconductor pattern, a gate electrode, a first electrode in contact with one side of the second oxide semiconductor pattern, a second electrode in contact with the other side of the second oxide semiconductor pattern, a first-second metal pattern disposed on the substrate to overlap the second oxide semiconductor pattern, and a second metal pattern disposed between the second oxide semiconductor pattern and the first-second metal pattern.

Abstract: Disclosed are a display panel, a pixel circuit arranged therein and a display device including the same. The display panel includes a sub-pixel of a first color, a sub-pixel of a second color, and a sub-pixel of a third color. Each of the sub-pixels of the first color, the second color, and the third color includes: a driving element including a first electrode coupled to a first node, a gate electrode coupled to a second node, and a second electrode coupled to a third node. The display panel includes a light emitting element including an anode electrode connected to the fourth node and configured to be driven by a current from the driving element; a first capacitor connected between the second node and the third node; and a second capacitor coupled between a constant voltage line and the third node or between the third node and the fourth node.
