Abstract
The present invention provides an OLED substrate and a manufacture method thereof. In the manufacture method of the OLED substrate of the present invention, by configuring the silicon film on the top surface of the pixel definition layer to make the top surface possess the excellent hydrophobic characteristic, the OLED material mistakenly sprayed onto the silicon film of the top surface does not stay on the silicon film but quickly falls into the pixel region of the substrate when the OLED material is ink jet printed in the pixel regions of the substrate to effectively prevent the issue that the OLED material stays on the top surface of the pixel definition layer or even slides into the adjacent pixel region to result in color mixing. In the OLED substrate, the color purity of the OLED light emitting layer is high and there is no problem of color mixing.
