Display device

A display device, comprising:

• a substrate including a plurality of substrate layers, a display area, and a non-display area surrounding the display area;
• an opening through the substrate in the display area;
• a transistor disposed over the substrate and including a first source-drain electrode pattern;
• a first planarization layer disposed on the first source-drain electrode pattern;
• a second source-drain electrode pattern disposed on the first planarization layer;
• a second planarization layer disposed on the second source-drain electrode pattern;
• a light emitting element disposed on the second planarization layer of the multi-layer stack;
• a plurality of encapsulation layers disposed on the light emitting element, the plurality of encapsulation layers comprising at least two layers with a different composition from each other;
• a touch sensor disposed over the encapsulation layer;
• a protection layer disposed on the touch sensor;
• and
• a third planarization layer disposed on the protection layer,
• wherein the non-display area comprises a bending area in which at least a portion of the substrate is bent around the display area, and
• wherein the third planarization layer extends from the display area into the bending area, and the touch sensor is disposed between the third planarization layer and the encapsulation layer in a cross-sectional view.

A display device, comprising:

• a first planarization layer disposed on the first source-drain electrode pattern;
• a second source-drain electrode pattern disposed on the first planarization layer;
• a second planarization layer disposed on the second source-drain electrode pattern;
• a light emitting element disposed on the second planarization layer;
• an encapsulation layer disposed on the light emitting element;
• a touch sensor disposed over the encapsulation layer;
