Abstract
A touch display apparatus senses a touch of a user, a tool or both. In the touch display apparatus, an upper electrode of a light-emitting device includes a first electrode portion overlapping an emission area, and a second electrode region spaced away from the first electrode region. A touch wire is disposed on an encapsulating element covering the light-emitting device. The touch wire includes a portion overlapping the second electrode region. Thus, in the touch display apparatus, a process of forming components for sensing the touch may be simplified.
Claims20
