Abstract

We purposed to fabricate an organic light-emitting device (OLED) using an Ag fiber electrode embedded in a polyvinyl butyral (PVB) substrate. Since the electrode is embedded in a flexible polymer substrate, the surface roughness is very low. Moreover, since the depth of the electrode can be freely adjusted, the resistance can be very low without decreasing the transmittance. As a result, we demonstrated that a OLED with external quantum efficiency of 10 % was successfully fabricated.
