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 6):
An OLED element, comprising\n an anode, and a hole injection layer, a hole transport layer, an emission layer, an electron transport layer and an electron injection layer and a first cathode are sequentially deposited on the anode; an organic material layer is formed corresponding to each of sub-pixels of the emission layer so as to adjust for adjusting microcavity effect on the first cathode by photolithography; and a second cathode is deposited and formed on the organic material layer; wherein the organic material layer is formed by following process positioning a photo mask on correspondingly position of the sub-pixel of emission layer, exposing to developing a negative photoresist by the photo mask; depositing the organic material layer for adjusting microcavity effect on position of the negative photoresist which is washed away by the developer solution and a remaining negative photoresist; peeling the remaining negative photoresist and the organic material layer positioned above thereon, and obtaining the organic material layer is corresponding to the sub-pixel of the emission layer; and repeating the above steps until obtaining the organic material layer which corresponding to each of the sub-pixels of the emission layer.
