Abstract
A hole transport polymeric compound and a polymer light emitting diode using the same. The hole transport polymeric compound includes a hole transport material, a thermal cross-linking agent containing an ethynyl group, and a compound represented by [Formula 1], and can be applied to a polymer light emitting diode. In addition, the hole transport polymeric compound has excellent hole transport capabilities and has stability in solvents so as to be insoluble in a solvent used upon stacking other organic layers and blocking electrons well.
