We herein report on polymer phosphorescent light-emitting devices doped with iridium complex. The emitting layer of poly(N-vinylcabazole) and tris(2-phenylpyridine)iridium was fabricated by low speed dip-coating of 10, $20{\mu}m$/s. The devices showed stable current increasing leakage current at turn-on voltage. Compared to conventional spin-coating based organic light-emitting devices, the driving voltage by dip-coating observed lower values of 5.8 and 6.7 V at the luminance of 100 Cd/$cm^2$.
