Abstract

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.
