Blue, green, and red electrophosphorescent polymer light‐emitting diodes have been fabricated on silver nanowire‐polymer composite electrode. The devices are 20%‐50% more efficient than control devices on ITO/glass and exhibit small efficiency roll‐off at high luminances. The blue PLEDs were repeatedly bent to 1.5 mm radius concave or convex with calculated strain in the emissive layer approximately 5% (tensile or compressive).
