Abstract
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.
