Abstract

The embodiment of the invention provides a display substrate and a display device, relates to the technical field of display, and can solve the problems that signal crosstalk between sub-pixels is caused by transverse transmission of carriers in a first light-emitting functional layer, and display is affected. The display substrate comprises a bottom plate and a pixel defining layer arranged on the bottom plate. The pixel defining layer comprises: a plurality of opening areas; a light-emitting layer arranged on the bottom plate and at least positioned at the opening areas; a first light-emitting function layer arranged between the light-emitting layer and the bottom plate and covering the pixel defining layer and the opening areas; a partition layer arranged between the first light-emitting function layer and the bottom plate and located in the opening areas; and a gap formed between the partition layer and the pixel defining layer. The display substrate is used in the display device.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display substrate and a display device. Background technique [0002] Due to the advantages of self-luminescence, low power consumption, wide viewing angle, fast response speed and high contrast ratio, the electroluminescent display device has become a mainstream development trend of display devices at present. [0003] An electroluminescent display device includes a display substrate and an encapsulation layer for encapsulating the display substrate. The display substrate includes an anode, a light emitting layer and a cathode which are stacked in sequence. In order to improve the luminous efficiency of the light-emitting layer, the display substrate further includes a hole injection layer (HIL for short) and / or a hole transport layer (HTL for short) arranged between the anode and the light-emitting layer, And an electron injection layer (election injection layer, EIL for s...
