Abstract: A touch display device and a touch display panel are provided. The touch display panel includes a bend area adjacent to the periphery of the touch display panel, and touch lines disposed in the bend area have zigzag shapes that extend at angles with respect to a bend axis about which the bend area is bent. A first dielectric layer includes a compensation pattern that is located in the bend area and includes an opening that extends in a direction parallel to the bend axis. A second dielectric layer protrudes into the opening of the compensation pattern in a depth direction. During bending of the bend area, this configuration disperses force applied to portions of the touch lines and the dielectric layers in the bend area. This can consequently prevent both cracking due to bending and moisture permeation due to cracks.

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.
