PLANARIZATION FILM FOR THE SUBSTRATE OF FLEXIBLE ORGANIC LIGHT EMITTING DIODES DEVICES AND FLEXIBLE ORGANIC LIGHT EMITTING DIODES DEVICES CONTAINING THE SAME

摘要

The present invention relates to a planarization film for a substrate of a flexible OLED device, and a flexible OLED device comprising the same. More particularly, the flexible OLED adopts a planarization film having a particular material and structure as a planarization layer on an upper surface of a substrate, thereby preventing and/or minimizing degradation of electrical characteristics of the OLED device caused by using a paper material as an OLED substrate material. Thus, the flexible OLED device secures physical properties such as low voltage, high efficiency, and high color purity. Preferably, the first planarization layer includes at least one type selected among PMF, PVP, PGMEA, PEGDMA, PPGDMA, PPGDA, PDEGDA, a POSS-based compound represented by chemical formula 1, a silazane compound represented by chemical formula 2, and a polysilazane-based compound.
