Abstract

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.
