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 display device includes first and second alignment electrodes disposed on a substrate, an alignment insulating film having a concave portion disposed between the first and second alignment electrodes, a light-emitting device disposed on the alignment insulating film, first and second electrodes electrically connected to the light-emitting device, a thin-film transistor connected to one of the first and second electrodes, and a plurality of insulating films providing a trench disposed on the concave portion, the trench having a larger width than the concave portion, thereby improving emission efficiency.

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.
