The alignment layer has been also used to fabricate polarized polymer light-emitting diodes (PLEDs). Highly polarized emission with an integrated dichroic ratio up to 28.6 and high luminance with more than 850 cd/m2 has been observed from the polarized PLED after adapting different kinds of cathode structures.
