Abstract
A display panel and a manufacturing method. The display panel includes a substrate; light-emitting devices and a pixel definition layer that are located at a side of the substrate; and a first spacer structure. The pixel definition layer includes apertures and bank portions, and the apertures include first apertures provided with the light-emitting devices and a second aperture. The first spacer structure is provided in the second aperture. Along a direction perpendicular to a plane of the substrate, one of the bank portions includes a first part, a distance from a surface of the first spacer structure away from the substrate to the substrate is d, and a distance from a surface of the first part away from the substrate to the substrate is d, where d>d. A transmission path of a lateral leakage current between two adjacent sub-pixels can be increased, thereby ameliorating undesirable lighting of sub-pixels.
