    Abstract: A display panel includes a pixel including sub pixels. The pixel includes a sub pixel area in which the sub pixels are disposed and a common area. The pixel includes a light emitting diode including an anode electrode and a cathode electrode, and the anode electrode is electrically connected to a first power line to which a high potential voltage is supplied. Each of the sub pixels includes a driving element in which a source is connected to a N1 node, a gate is connected to a N2 node, and a drain is connected to a N3 node, a capacitor connected to the N2 node and a N4 node; a N1 switching circuit connected to the N1 node; a N2 switching circuit connected to the N2 node; a N3 switching circuit connected to the N3 node; and a N4 switching circuit connected to the N4 node.

    Abstract: Disclosed is a display device that includes a display area having an appearance of a specific color in a non-driving state or displaying a specific screen by using PDLC to improve esthetic appearance as in a home appliance. The display device comprises a reflective dispersed layer arranged on a display panel, wherein the reflective dispersed layer includes a PDLC layer between a first substrate and a second substrate, and a transflective layer arranged between the PDLC layer and the second substrate to transmit light externally emitted from the display panel and reflect externally incident light.

    Abstract: An electroluminescent display device having pixel driving circuit is disclosed. The display device includes a pixel that includes sub-pixels and is divided into a sub-pixel area where the sub-pixels and a first pixel driving circuit are disposed and a common area where a second pixel driving circuit is disposed. Each of the sub-pixels includes a light emitting element including an anode electrode and a cathode electrode. The anode electrode is connected to a first common line which is connected to the second pixel driving circuit.
