Touch display device and touch display panel having a bend area including a dielectric layer with a compensation pattern

A panel, comprising:

• an encapsulation layer;
• a plurality of touch lines on the encapsulation layer;
• a first dielectric layer on and in contact with the plurality of touch lines, the first dielectric layer including a compensation pattern having an opening in a bend area positioned adjacent to a periphery of the panel, the opening exposes portions of the plurality of touch lines;
• and
• a second dielectric layer on the first dielectric layer, the second dielectric layer protrudes into the opening included in the first dielectric layer such that the second dielectric layer contacts with the plurality of touch lines,
• wherein the second dielectric layer protrudes into the opening in a depth direction to be deposited in the opening, and a thickness of the second dielectric layer in the opening, is greater than a depth of the opening.

A device, comprising:

• a flexible substrate having an active area, a bend area, and a link area between the active area and the bend area;
• a touch layer on the flexible substrate, the touch layer including a plurality of touch electrodes, each of the plurality of touch electrodes including:
• a first portion in the link area,
• a second portion in the bend area, and
• a third portion in the bend area, the second portion and the third portion being connected to the first portion, at least one of the plurality of touch electrodes including the second and third portions in the link area;
• a first dielectric layer on and in contact with the touch layer in the bend area, the first dielectric layer including an opening;
• a compensation pattern in the bend area, the compensation pattern including a groove in the first dielectric layer that exposes at least a portion of the touch layer in the bend area;
• and
• a second dielectric layer on the first dielectric layer and protruding into the groove such that the second dielectric layer contacts with the plurality of touch lines,
• wherein the second dielectric layer protrudes into the opening in a depth direction to be deposited in the opening, and a thickness of the second dielectric layer in the opening is greater than a depth of the opening.
