ABSTRACT:
An organic electroluminescent device having the hole-transport layer in which the hole-transport material is dispersed in the resin binder having a glass transition temperature of not less than 170.degree. C.
Since the above organic electroluminescent device has the hole-transport layer exhibiting sufficient durability and higher hole-transport property, it is excellent in luminous efficiency, luminance and stability.
