    Abstract: A display apparatus having improved reliability and preventing or reducing damage to an organic light-emitting diode (OLED), and a method of manufacturing the display apparatus by arranging a protective layer on an opposite electrode during a photo-patterning process, are provided. The display apparatus includes: a substrate; a pixel electrode on the substrate; a pixel defining layer on the pixel electrode, the pixel defining layer having a first opening that exposes a center of the pixel electrode; an auxiliary electrode on the pixel defining layer; an intermediate layer on the pixel electrode; an opposite electrode facing the pixel electrode with the intermediate layer therebetween; a first protective layer on the opposite electrode; and a contact electrode on the first protective layer, the contact electrode electrically contacting the auxiliary electrode and the opposite electrode.

    Abstract: A method includes: forming first and second pixel electrodes on a substrate; exposing upper surfaces of the first and second pixel electrodes; forming a pixel defining layer covering edges of the first and second pixel electrodes; sequentially forming a first lift-off layer, a first shape memory alloy layer, and a first photoresist; forming a first opening exposing an upper surface of the first pixel electrode by patterning the first lift-off layer, the first shape memory alloy layer, and the first photoresist; forming, on the first pixel electrode and the first photoresist, a first organic functional layer including a first emission layer; deforming an end portion of the first shape memory alloy layer, in the first opening, in a direction away from a horizontal surface of the substrate; forming a first protection layer over the first organic functional layer; and removing a remainder of the first lift-off layer.

    Abstract: A display apparatus includes a first pixel electrode and a second pixel electrode spaced apart from each other and disposed on a substrate, a pixel definition layer including a first inner surface defining a first opening exposing a portion of the first pixel electrode and a second inner surface defining a second opening exposing a portion of the second pixel electrode, a first lyophobic pattern covering the first inner surface and a portion of an upper surface of the pixel definition layer adjacent to the first inner surface and including a lyophobic material, and an opposite electrode disposed on the first pixel electrode and the second pixel electrode. The first lyophobic pattern partially surrounds the first opening in a plan view.
