Abstract
The present disclosure discloses an organic electroluminescent device, a manufacturing method thereof, and a display device. The organic electroluminescent device includes a base substrate. A light control layer is disposed on the base substrate. The light control layer includes a light transmitting structure and a light shielding structure disposed in the same layer and spaced from each other. The light shielding structure has a height h. The light transmitting structure has a width b. The light control layer is used for shielding and transmitting light emitted by the organic electroluminescent device so that an exit angle of the emitted light is within an angle θ.
