Abstract: A display apparatus can include pixel areas and a contact area between the pixel areas. An auxiliary electrode can be disposed in the contact area. Each of the pixel areas can include a light-emitting device on a device substrate. An insulating layer including at least one contact hole overlapping with the contact area can be disposed on the device substrate. A connection electrode electrically connected to the auxiliary electrode can extend along a sidewall and a bottom surface of the contact hole. A light-emitting layer and a second electrode of the light-emitting device in each pixel area can extend inside of the contact hole. Thus, in the display apparatus, a process of forming the second electrode and the connection electrode can be simplified, and damage of the light-emitting device due to a process of connecting the second electrode and the connection electrode can be minimized.

Abstract: A display apparatus including an auxiliary electrode are disclosed. The display apparatus includes a contact area between pixel areas. The auxiliary electrode is within the contact area. A planarization layer covering the auxiliary electrode includes an inclined surface overlapping with the contact area and an upper surface extending from the inclined surface. A connection electrode covering the inclined surface and the upper surface of the planarization layer is connected to the auxiliary electrode. A light-emitting device on each pixel area has first and second electrodes and a light-emitting layer. The light-emitting layer and the second electrode extends onto the connection electrode. The light-emitting layer exposes a portion of the connection electrode by a reflow pattern, and the second electrode is in contact with the portion of the connection electrode exposed by the light-emitting layer. Thus, a process of connecting the second electrode and the connection electrode may be simplified.

Abstract: A touch display apparatus is provided. The touch display apparatus may include touch electrodes on an encapsulating layer covering light-emitting devices. An auxiliary line crossing a display area in which the light-emitting devices are disposed may be disposed on the encapsulating layer. The auxiliary line may be electrically connected to a power voltage supply line at the outside of the display area. Each of the light-emitting devices may include a first emission electrode, a light-emitting layer and a second emission electrode, which are stacked on an emission area defined by a bank insulating layer. The second emission electrode of each light-emitting device may be electrically connected to the auxiliary line on the bank insulating layer. Thus, in the touch display apparatus, a luminance deviation due to a voltage drop may be prevented or at least reduced.

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 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.
