摘要:
The invention provides an OLED device with improved light out-coupling comprising an electroluminescent layer stack (2) on top of a substrate (1), where the electroluminescent layer stack (2) comprises an organic light-emitting layer stack (6) with one or more organic layers sandwiched between a first electrode (3) facing towards the substrate (1) and a second electrode (7) to apply a driving voltage to the organic light-emitting layer stack (6), and a first electron transport layer stack (4a) arranged between the organic light emitting layers stack (6) and the second electrode (7), wherein the electron transport layer stack (4a) comprises an electron transport layer (41) made of a first electron transport material having a low refractive index and at least one n-doped layer (40, 42). The invention further relates to a method to manufacture these OLED devices.
