An organic electroluminescence device comprising organic functional layers disposed between a positive electrode and a negative electrode arranged in pair opposite to each other and composed of three or more thin films including a luminescent layer of organic compound. The organic functional layers comprise a first layer and a second layer arranged in pair and each constituted of an organic compound whose glass transition temperature is a first temperature or above and further a third layer interposed between the first layer and the second layer and constituted of an organic compound whose glass transition temperature is below the first temperature.
