Provided are a vertical field-effect transistor, a method of manufacturing the same, and a display device having the same. The method is highly reproducible and can be used to manufacture a vertical organic field-effect transistor at a low cost. In addition, the method does not require photolithography and a shadow mask. In the vertical field-effect transistor, a source electrode is formed on a substrate, and an insulating layer and discontinuous gate electrodes are formed. Then, a charge carrier block layer, an organic semiconductor material, and a drain electrode are formed. The gate electrodes are formed using nanoparticles.
