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

Claim 16:
17. 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 insulating layer on the encapsulating element;
a touch structure on the encapsulating element, the touch structure including touch electrodes on the touch insulating layer;
a touch routing line connecting the touch structure to the pad, the touch routing line including a lower routing electrode layer between the encapsulating element and the touch insulating layer, an upper routing electrode layer on the touch insulating layer and a routing cover layer covering the upper routing electrode; and
a black matrix and a color filter on the touch structure the color filter overlapping with the light-emitting device, the black matrix being disposed side by side with the color filter,
wherein the pad cover layer fully covers an outermost side surface of the pad electrode layer,
wherein the black matrix covers the touch electrodes of the touch structure and a portion of the touch routing line,
wherein the pad cover layer and the routing cover layer have an etch selectivity with the black matrix and the color filter, and
wherein the upper routing electrode layer is electrically connected to the lower routing electrode layer.
