摘要： An organic light-emitting display panel, divided into a display region and a non-display region surrounding the display region, includes a substrate; an array layer formed over the substrate; a pixel defining layer formed on the surface of the array layer away from the substrate; and a plurality of organic light-emitting devices formed in a plurality of openings of the pixel defining layer. The plurality of organic light-emitting devices are disposed in the display region, and each organic light-emitting device includes an anode, an organic light-emitting layer, and a cathode sequentially formed on the substrate. The organic light-emitting display panel also includes a plurality of support units disposed in the non-display region. At least one support unit of the plurality of support units is disposed on the surface of the pixel defining layer away from the substrate.

摘要： The present disclosure provides organic light-emitting display panel, manufacturing method, and organic light-emitting display device. Organic light-emitting display panel includes: array substrate, planarization layer, pixel defining layer, and multiple organic light-emitting devices. The pixel defining layer has multiple pixel apertures, each of which is provided therein with at least two organic light-emitting devices for emitting a same color. Anodes of the organic light-emitting devices are one-to-one electrically connected to pixel driving circuits on the array substrate. The planarization layer is provided with multiple grooves, which are disposed between any adjacent two organic light-emitting devices in each pixel aperture and are filled with hydrophobic layer. The hydrophobic layer is provided with multiple trenches. Extending direction of each groove is the same as extending direction of each trench. The organic light-emitting function layer breaks at each trench. The present disclosure can improve display effect of organic light-emitting display panel.
