A touch display apparatus is provided. The touch display apparatus may include an encapsulating unit covering light-emitting devices, a touch sensor on the encapsulating unit, and a black matrix on the touch sensor. The touch sensor may include first touch electrode disposed side by side, first bridge electrodes connecting the first touch electrodes in a first direction, second touch electrodes disposed between the first touch electrodes, and second bridge electrodes connecting the second touch electrode in a second direction perpendicular to the first direction. The second bridge electrodes may cross the first bridge electrodes. The second bridge electrodes may be disposed on a layer different from the second touch electrodes. For example, the second touch electrodes may be disposed on the same layer as the first touch electrodes and the first bridge electrodes. The planar shape of the black matrix may be the same as the planar shape by the first touch electrodes, the first bridge electrodes and the second touch electrodes. Thus, in the touch display apparatus, the process efficiency may be improved.

Touch display apparatus and method of manufacturing the same

Disclosed is a display device capable of reducing the thickness and the weigh thereof. In an organic light-emitting diode display device having a touch sensor, a plurality of routing lines, which are connected respectively to a plurality of touch sensors disposed on an encapsulation unit, are disposed on different planes so as to overlap each other and are electrically connected to each other through a plurality of routing contact holes. Thereby, a connection fault between the routing lines is prevented. In addition, through the provision of the touch sensors above the encapsulation unit, a separate attachment process is unnecessary, which results in a simplified manufacturing process and reduced costs.

Display device

A touch display apparatus is provided. The touch display apparatus may include a light-emitting device and a touch sensor. The touch sensor may be disposed on an encapsulating unit covering the light-emitting device. A photo-electric device may be disposed between the encapsulating unit and the touch sensor. The photo-electric device may be disposed outside an emission area in which the light-emitting device is disposed. A light-absorbing layer of the photo-electric device may overlap at least one of touch electrodes and bridges of the touch sensor. Thus, the touch display apparatus may increase the time that the touch display apparatus is used without external power source connected by using the electrical energy generated by the photo-electric device.
