ELECTROLUMINESCENT COMPONENT, MANUFACTURING METHOD THEREFOR, DISPLAY SUBSTRATE, AND DISPLAY DEVICE

摘要

An electroluminescent component, a manufacturing method therefor, a display substrate, and a display device, related to the technical field of displays, obviating the need for reducing the thickness of a metal cathode to increase the overall light emission rate of an OLED component, thus ensuring great display effects thereof. The electroluminescent component comprises: a method cathode layer (20) arranged on a base substrate (10), a functional layer (30), and a transparent cathode layer (40), where the transparent cathode layer (40) is arranged at a light-emitting side of the electroluminescent component, and the functional layer (30) is arranged between the metal cathode layer (20) and the transparent cathode layer (40), and comprising: an electron transfer layer (31), a light-emitting layer (32), and a hole transport layer (33) in a sequence away from the metal cathode layer (20). This is for use in manufacturing the electroluminescent component and the display substrate and the display device comprising the electroluminescent component.
