Abstract
A touch display apparatus senses a touch of a user and/or a tool. In the touch display apparatus, an upper electrode of each light-emitting device may include a first electrode region overlapping with an emission area and a second electrode region being spaced away from the first electrode region. The second electrode region may be connected to a link wire different from the first electrode region. Thus, in the touch display apparatus, at least one of the first electrode region and the second electrode region of each upper electrode may be used for sensing the touch of the user and/or the tool. Therefore, in the touch display apparatus, a process of forming components for sensing the touch may be simplified.
