Abstract: A perovskite light emitting diode having degradation of the characteristics of the light emitting device, caused by PEDOT:PSS can be improved by replacing PEDOT:PSS contained in a conventional hole transport layer with an anionic conjugated polymer having ammonium-based counter ions, and the light emission characteristics can be greatly improved by passivating defects of a perovskite light emitting layer with a hole transport layer containing a conjugated polymer and increasing crystal growth.

Abstract: The present invention relates to an optical element capable of simultaneously outputting sound from the surface of a display device with an image, the optical element comprising: a first electrode member; a first dielectric elastomer layer disposed on the first electrode member; a second electrode member disposed on the first dielectric elastomer layer; and an optical crystal layer disposed on the second electrode member. Accordingly, in the present invention, image and sound are implemented simultaneously, and thus, it is possible to prevent defects due to mismatching of the image and the sound, and a separate sound system is not required when the display device is manufactured using the optical element, thereby making it possible to reduce components of an electronic product including the display device and reduce the manufacturing cost.
