Abstract
Disclosed is a display device capable of reducing the thickness and the weigh thereof. A display device having a touch sensor realizes electrical connection of a routing line and a touch pad via an auxiliary conductive layer, which is connected to the routing line under an encapsulation unit, even if a disconnection fault occurs in the routing line, thereby achieving increased yield and reliability. In addition, through the provision of a touch sensor disposed above the encapsulation unit, a separate attachment process is unnecessary, which results in a simplified manufacturing process and reduced costs.
Claims20
A display device, comprising:
- a light-emitting element disposed on a substrate;
- an encapsulation unit disposed on the light-emitting element;
- an element insulation layer between the encapsulation unit and the substrate;
- a touch sensor disposed on the encapsulation unit;
- a touch pad connected to the touch sensor;
- a routing line disposed between the touch pad and the touch sensor, the routing line electrically coupling the touch pad to the touch sensor;
- and
- an auxiliary conductive layer connected to the touch pad and the routing line through an auxiliary contact hole penetrating through at least one of the encapsulation unit and the element insulation layer;
- wherein at least a portion of the auxiliary conductive layer is disposed between the substrate and the routing line.
