To take advantages two polymer materials for hole transport layer, it blended in solvent with optimized ratio. However, polymer-entanglement occurs when polymers are dissolved in solvent. It makes the surface rough, which causes leakage current. We introduce to decrease polymer-entanglement. It can decrease leakage current, then improve the QD-LED performance.
