A light-emitting device including a semiconductor nanocrystal layer and a method for producing the light-emitting device are provided. The light-emitting device includes a semiconductor nanocrystal layer whose voids are filled with a filling material. According to the light-emitting device, since voids formed between nanocrystal particles of the semiconductor nanocrystal layer are filled with a filling material, the occurrence of a current leakage through the voids is minimized, which enables the device to have extended service life, high luminescence efficiency, and improved stability.

Disclosed is a light-emitting device. The light-emitting device comprises a blue light-emitting source and a light-emitting source. The light-emitting source includes first semiconductor nanocrystals and second semiconductor nanocrystals. The first and second nanocrystals emit lights of different wavelengths from each other to produce a color complementary to blue. The first and second semiconductor nanocrystals are spatially clustered to form first and second composites respectively.
