Abstract:
An OLED element and a method of manufacturing thereof are provided, The method of manufacturing OLED element includes step S 1,  sequentially depositing a hole injection layer, a hole transport layer, an emission layer, an electron transport layer and an electron injection layer and a first cathode on an anode; step S 2,  forming sub-pixels corresponding to each of the emission layers and an organic material layer for adjusting microcavity effect by photolithography; step S 3,  depositing a second cathode on the organic material layer. The disclosure provides a manufacture which adds conducting organic material layer between two cathodes by photolithography which is not effect to OLED material. According to adjust thickness of layer to enhance microcavity effect, the photolithography is different than the photolithography of manufacture CF and anode, it doesn't need fine metal mask, which save cost and time of manufacture OLED and enhance process efficiency.

Claim (Index 1):
A method of manufacturing OLED element, comprising step S 1 , sequentially depositing a hole injection layer, a hole transport layer, an emission layer, an electron transport layer and an electron injection layer and a first cathode on an anode;\n step S 2 , forming an organic material layer corresponding to each of sub-pixels of the emission layers so as to adjust microcavity effect by photolithography; step S 3 , depositing a second cathode on the organic material layer; wherein the specifically step S 2  comprising step S 21 , coating a negative photoresist compatible with organic material on the first cathode; step S 22 , positioning a photo mask on correspondingly position of the sub-pixel of emission layer, exposing to developing the negative photoresist by the photo mask; step S 23 , depositing the organic material layer for adjusting microcavity effect on the position of the negative photoresist which is washed away by the developer solution and a remaining negative photoresist; step S 24 , peeling the remaining negative photoresist and the organic material layer positioned above thereon, and obtaining a remaining organic material layer is corresponding to the sub-pixel of the emission layer; step S 25 , repeating the steps S 21 -S 24  until obtaining the remaining organic material layer which corresponding to each of the sub-pixels of the emission layer.
