Abstract:
A substrate for an organic light-emitting device, a method for manufacturing the substrate for an organic light-emitting device, and a display device are provided. The substrate for an organic light-emitting device includes a base substrate, a pixel definition layer on the base substrate, and an organic light-emitting device in each of the pixel regions. The pixel definition layer defines a plurality of pixel regions, each of the pixel regions has a top opening and a lower opening along a thickness direction of the base substrate, the lower opening is in the top opening so that each of the pixel regions has a slope extending from the top opening to the lower opening, and boundaries of the top openings adjacent to each other are intersected with each other.
