1. A touch display apparatus comprising:
a device substrate;
a plurality of light-emitting devices on a display area of the device substrate;
an encapsulating layer on the device substrate, the encapsulating layer covering the plurality of light-emitting devices;
a touch insulating layer on the encapsulating layer;
a first touch line on the touch insulating layer, the first touch line including first touch electrodes and first bridge electrodes that electrically connect the first touch electrodes in a first direction;
a second touch line including second touch electrodes and second bridge electrodes, the second bridge electrodes between the encapsulating layer and the touch insulating layer, and electrically connecting the second touch electrodes in a second direction that is different from the first direction;
a touch passivation layer on the touch insulating layer, the first touch electrodes, the first bridge electrodes, and the second touch electrodes disposed between the touch insulating layer and the touch passivation layer;
a first light-blocking pattern on the touch passivation layer, the first light-blocking pattern electrically connected to the first touch electrodes and the first bridge electrodes;
a second light-blocking pattern on the touch passivation layer, the second light-blocking pattern electrically connected to the second touch electrodes; and
a power voltage supply line on the encapsulating layer, the power voltage supply line extending along an edge of the display area, the power voltage supply line including a first supply line and a second supply line on the first supply line,
wherein the first light-blocking pattern and the second light-blocking pattern have a reflectance that is less than reflectances of the first touch electrodes, the first bridge electrodes, and the second touch electrodes, and
wherein the second supply line is electrically connected to the first supply line, and the second supply line includes the same material as the first light-blocking pattern.
