Abstract
Embodiments of the invention provide an organic light-emitting display (OLED) panel and a manufacturing method for the OLED panel, which comprises providing a substrate comprising a first electrode layer which comprises a plurality of first electrodes spaced apart from each other, forming an insulating layer on the substrate, etching off the insulating layer over the first electrodes by a photolithography process to form a pattern of sub-pixel depositing areas and forming organic light-emitting layers for desired colors within the sub-pixel depositing areas, and forming a second electrode layer on the insulating layer and the organic light-emitting layers. Embodiments of the invention can exactly prepare the organic light-emitting layers to improve yield.
