3 Manufacturing method of three-dimensional nanoporous layer and diffuser and OLED using the three-dimensional nanoporous layer

摘要

The present invention relates to a diffuser using a porous layer having a plurality of irregularly distributed pores formed in a three-dimensional multi-layer, an organic light-emitting device, and a method of manufacturing the porous layer. More particularly, A second step of spin-coating the solution in a predetermined humidity atmosphere, and a third step of drying the spin-coated polymer layer.In the first step, a first step of adjusting the concentration of the polymer contained in the solution or a first step of mounting a first base material on a turntable of a spin coating apparatus and dropping a solution on the first base material, 2 /RTI The second step may further include a second step of controlling the humidity or the spin coating speed to form pores using the elastic bouncing mechanism, The predetermined humidity atmosphere in step 2-1 may be adjusted through an ultrasonic humidifier.According to another embodiment of the present invention, a diffuser may include a porous layer having a plurality of irregularly distributed pores formed in a three-dimensional multi-layered structure, and a polarizing film The polarizer film may further include a protective film on an upper portion of the polarizer film.According to another embodiment of the present invention, there is provided a light emitting device including a first electrode, a light emitting layer provided on the first electrode, a second electrode provided on the light emitting layer, and a transparent substrate provided on the second electrode, Wherein the polarizing film is disposed on top of the porous layer, wherein the polarizing film is formed on the transparent substrate according to the manufacturing method of the porous layer.
