Abstract: A quantum dot composite including a quantum dot and a quantum dot ligand located on a surface of the quantum dot is provided. The quantum dot ligand includes a hydrophilic linking portion including an oxygen atom, a bonding portion linked to one side of the linking portion and including different functional groups bonded to the quantum dot, and a terminal portion linked to the linking portion at a side opposite to the linking portion. The quantum dot ligand is configured to prevent or reduce aggregation of quantum dots and improve their dispersion in a solvent thereby improving the light and/or heat resistance of electronic apparatus that utilize the quantum dot composite.

Abstract: A method of manufacturing an organic light-emitting display apparatus includes forming a pixel electrode, a bus electrode and a pixel defining layer on a same layer on a substrate, the pixel defining layer exposing a center of the pixel electrode and a portion of the bus electrode, forming an intermediate layer on the pixel-defining layer and on the pixel electrode and the bus electrode, orienting the substrate such that the intermediate layer is located underneath the substrate, forming an opening in the intermediate layer by irradiating the intermediate layer with a laser beam from underneath the intermediate layer to remove the intermediate layer on the bus electrode, exposing at least a portion of the bus electrode, and forming an opposite electrode such that the opposite electrode contacts the bus electrode via the opening in the intermediate layer.
