Abstract

The embodiment of the invention provides a display substrate, an electroluminescent display panel and an electroluminescent display device, which relate to the technical field of display and can be used to solve the problem of high temperature of the electroluminescent display panel. The display substrate includes a display area and a peripheral area. The display area includes a plurality of light-emitting areas and non-light-emitting areas. The display substrate includes a base, and a first electrode layer, a light-emitting functional layer and a second electrode layer arranged on the base inturn. The first electrode layer includes a plurality of first electrodes, of which each is located in one light-emitting area. The display substrate also includes a first thermal conductive layer arranged between the light-emitting functional layer and the second electrode layer and at least located in the light-emitting areas.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate, an electroluminescence display panel and an electroluminescence display device. Background technique [0002] Electroluminescent display devices have a series of advantages such as self-luminescence, fast response speed, high brightness, large viewing angle, and flexible display, so they have become a type of display device with great competitiveness and development prospects. [0003] The electroluminescent display device includes an anode, a light-emitting functional layer and a cathode which are stacked in sequence, and the light-emitting functional layer will generate a large amount of heat during the process of emitting light. Since the luminance of the light-emitting functional layer varies with temperature, the problem of uneven display luminance of the electroluminescence display device will be caused. In addition, an excessively high temperature wi...
