Abstract

The present disclosure provides an OLED component, a method for manufacturing the same and an OLED display. The OLED component includes a baseplate; a pixel define layer, an insulation layer and an organic light-emitting unit successively disposed on the baseplate; wherein the pixel define layer defines a light-emitting area, the organic light-emitting unit is located in the light-emitting area, and the insulation layer is arranged between the pixel define layer and the organic light-emitting unit. Therefore, the implementation of the present disclosure may prevent impurities in the pixel define layer from entering into the organic light-emitting unit.
