    Abstract: A transparent touch display apparatus including a device substrate, a touch electrode and a routing line. The device substrate may include an emission area and a transmission area. The touch electrode may be disposed on the transmission area of the device substrate. The routing line may be disposed outside the emission area and the transmission area of the device substrate. A transmittance of the touch electrode may be higher than a transmittance of the routing line. Thus, in the transparent touch display apparatus, the reliability of the touch detection may be improved.
