摘要:
An organic light emitting diode (OLED) device is disclosed. In one embodiment, the OLED device includes: a substrate (110) and a first thin film (112) formed on the substrate, wherein the first thin film (112) comprises first and second surfaces opposing each other, wherein the first surface contacts the substrate (110), and wherein a plurality of protrusions and depressions (112a) are alternately formed on the second surface of the first thin film (112). The OLED device further includes a second thin film (114) formed on the protrusions and depressions (112a) of the first thin film (112), a first electrode (191) formed on the second thin film (114), an organic light emitting member (370) formed on the first electrode (191) and a second electrode (270) formed on the organic light emitting member (370).
