Provided is an organic electroluminescent device (organic EL device) that is improved in luminous efficiency, sufficiently secures driving stability, and has a simple construction. The organic electroluminescent device includes an organic layer including a light-emitting layer between an anode and cathode laminated on a substrate, and at least one layer of the organic layer contains a carbazole compound represented by the following formula (1). It is advantageous to incorporate the carbazole compound as a host material into the light-emitting layer. In the formula (1), A represents a direct bond or an n-valent group, E represents oxygen or sulfur, and n represents an integer of 2 to 4.
