Assignee: LG DISPLAY CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H  G | IPC G  H

Claim 0:
1. 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.
