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.
