Abstract
A display apparatus is provided. The display apparatus includes a pad spaced away from an encapsulating element. The pad can have a stacked structure of a pad electrode layer and a pad cover layer. A side surface of the pad electrode layer can be covered by the pad cover layer. Thus, in the display apparatus, damage of the pad electrode layer due to a subsequent process can be prevented and as such, the reliability of an external signal transmitted through the pad can be improved.
Claims19
A display apparatus comprising:
- a device substrate including a display area and a non-display area;
- a light-emitting device on the display area of the device substrate;
- a pad on the non-display area of the device substrate, the pad having a stacked structure composed of a pad electrode layer and a pad cover layer;
- an encapsulating element covering the light-emitting device, the encapsulating element being spaced away from the pad;
- a touch structure on the encapsulating element, the touch structure including touch electrodes and bridge electrodes, the touch electrodes and the bridge electrodes being disposed outside the light-emitting device;
- a touch routing line extending along a surface of the encapsulating element to electrically connect the touch structure to the pad, the touch routing line having a stacked structure of an upper routing electrode layer and a routing cover layer;
- a touch insulated layer on the encapsulating element;
- a color filter on the touch structure, the color filter overlapping with the light-emitting device;
- and
- a black matrix disposed side by side with the color filter and on a same layer as the color filter, the black matrix covering the touch electrodes, the bridge electrodes and a portion of the touch routing line,
- wherein the pad cover layer fully covers an outermost side surface of the pad electrode layer,
- wherein a side surface of the upper routing electrode layer is covered by the routing cover layer,
- wherein the pad cover layer and the routing cover layer have an etch selectivity with the black matrix and the color filter,
- wherein the touch electrodes of the touch structure and the upper routing electrode layer of the touch routing line are disposed on the touch insulating layer,
- wherein the touch routing line includes a lower routing electrode layer between the encapsulating element and the touch insulating layer, and
- wherein the upper routing electrode layer is electrically connected to the lower routing electrode layer.
