Abstract

An electroluminescence display device according to an embodiment includes a plurality of sub-pixels. Each of the plurality of sub-pixels includes a Node-A electrically connected to an electrode of a storage capacitor and a gate electrode of a P-type driving transistor, an N-type switching transistor configured to switch an electrical connection between a Node-B electrically connected to a data line and the Node-A, a Node-C configured to supply ELVDD voltage and electrically connected to another electrode of the storage capacitor and a first electrode of the P-type driving transistor, a Node-D configured to supply current to an electroluminescence diode and electrically connected to a second electrode of the P-type driving transistor, and a first transistor configured to switch an electrical connection between the Node-A and the Node-D.
