Abstract: Provided is a display device. The display device includes a substrate including a plurality of pixels, an adhesive layer on the substrate, a light emitting diode on the adhesive layer, a planarization layer surrounding the light emitting diode, a connection electrode on the planarization layer, and a transparent protective layer on the connection electrode. At least one layer of the adhesive layer, the planarization layer, and the transparent protective layer includes a plurality of multi-shell structured particles. The multi-shell structured particles are included in the display device so that the adhesion and the adhesion holding power between the light emitting diode and the driving panel are improved to increase the product yield and improve the luminance of the light emitting diode, thereby providing a display device with low power consumption.

Abstract: A light emitting display panel includes a first emission area, a second emission area, and a third emission area spaced apart from each other and emitting different colors of light and a photochromic layer surrounding each of the first, second, and third emission areas and disposed in a non-emission area. When the first emission area, the second emission area, and the third emission area emit light, the photochromic layer is in a transparent state. When light of a wavelength band shorter than visible light is incident on the photochromic layer, the photochromic layer is in an opaque state.

Abstract: Disclosed is a display apparatus with integrated touch screen, in which a relative permittivity of an encapsulation layer is reduced, thereby increasing touch sensitivity. The display apparatus with integrated touch screen includes a light emitting layer disposed on a lower substrate, an encapsulation layer disposed on the light emitting layer, and a touch electrode disposed on the encapsulation layer. The encapsulation layer includes a first elastic layer disposed on the light emitting layer, a low dielectric layer disposed on the first elastic layer, and a second elastic layer disposed on the low dielectric layer. A relative permittivity of the low dielectric layer is 2.5 to 2.8.
