Abstract
An electroluminescent device and a display device are provided. The electroluminescent device includes: a base substrate (100), a first surface of which is provided with a luminous element (110); a first substrate (210) having a first groove arranged to be opposed to the first surface of the base substrate (100); a sealing element (300) hermetically secured with a wall of the first groove, protruding from a notch of the first groove, and having a sealing groove provided to be opposed to a first surface of the base substrate (100); a part of the sealing element (300) protruding from the notch of the first groove is hermetically secured with the base substrate (100), and the luminous element (110) is arranged within the sealing groove. The electroluminescent device and display device depress the probability of the moisture in the air entering the sealing element and contacting with the luminous element, thus improving the performance and life of the electroluminescent device.
