Abstract: A display apparatus includes a light-emitting device and an optical lens are stacked on an emission area of a device substrate. A black matrix and a touch electrode may be disposed on a non-emission area of the device substrate. An encapsulation unit covering the light-emitting device and an optical insulating layer covering the black matrix may be disposed on the emission area and the non-emission area of the device substrate. The touch electrode and the optical lens may be disposed on the optical insulating layer. A lens barrier may be disposed on the optical insulating layer. The optical lens may be surrounded by the lens barrier. Thus, in the display apparatus, a deform of the optical lens due to a reflow process may be prevented. Therefore, in the display apparatus, decreasing the quality of the image due to a process of forming the optical lens may be prevented.

Abstract: A touch display apparatus is provided. The touch display apparatus may include a touch sensor on an encapsulating layer that covers light-emitting devices. The touch sensor may include first touch electrodes connected in a first direction by first bridge electrodes, and second touch electrodes connected by second bridge electrodes in a second direction that is different from the first direction. A light-blocking pattern may be disposed on the first touch electrodes and the second touch electrodes. The light-blocking pattern may include a conductive material having a lower reflectance than reflectances of the first touch electrodes and the second touch electrodes. The light-blocking pattern may comprise of a first light-blocking pattern electrically connected to the first touch electrodes and a second light-blocking pattern electrically connected to the second touch electrodes. Thus, in the touch display apparatus, the reliability of the touch sensor may be improved by the light-blocking pattern.

Abstract: A touch display apparatus is provided. The touch display apparatus may include a touch sensor on an encapsulating layer that covers light-emitting devices. The touch sensor may include touch electrodes and bridge electrodes electrically connecting between the touch electrodes. Each of the touch electrodes may be electrically connected to a corresponding touch pad by one touch routing line from touch routing lines. The touch routing lines may include first routing lines and second routing lines disposed on a different layer from the first routing lines. Thus, in the touch display apparatus, an area occupied by the touch routing lines may be reduced.
