An electroluminescent device includes an anode, a cathode, a light-emitting layer between the anode and the cathode, and a hole transport layer between the anode and the light-emitting layer. The light-emitting layer includes inorganic light-emitting nanomaterials, the hole transport layer includes an organic hole transport material, and the HOMO HTM of the organic hole transport material is ≤‑5.4eV, and ∣(HOMO‑1)HTM‑HOMO HTM ∣≥0.3eV. |
