1. A touch display apparatus comprising:
a device substrate including an emission area in which light-emitting devices are disposed, and a transmission area spaced apart from a first electrode of each light-emitting device from the light-emitting devices such that the transmission area is non-overlapping with the first electrode of each light-emitting device;
an encapsulating element on the light-emitting devices, the encapsulating element extending on the transmission area;
a routing line on the encapsulating element, the routing line spaced apart from the emission area and the transmission area; and
a touch electrode having a transmittance that is greater than a transmittance of the routing line, the touch electrode electrically connected to the routing line between the emission area and the transmission area,
wherein the touch electrode has a mesh shape overlapping with the transmission area, which extends in a first direction and a second direction different from the first direction.
