Abstract

Embodiments of the present invention provide a substrate for display and a display device, which relate to the field of display technology and can solve the problem of lateral transport of carriers in the first light-emitting functional layer, resulting in signal crosstalk between sub-pixels and affecting display. The display substrate includes a base plate and a pixel defining layer disposed on the base plate; the pixel defining layer comprises a plurality of opening areas; a light emitting layer disposed on the base plate and at least located in the opening areas; disposed on the base plate Between the light-emitting layer and the bottom plate, and covering the pixel defining layer and the first light-emitting functional layer of the opening area; arranged between the first light-emitting functional layer and the bottom plate, and located in the opening an isolation layer of a region; there is a gap between the isolation layer and the pixel defining layer. used in display devices.

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...
