Title:
DISPLAY SUBSTRATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/206129
Kind Code:
A1
Abstract:
The present disclosure provides a display substrate and a display device. The display substrate comprises a base and a plurality of sub-pixels provided on the base; the sub-pixels each comprise a sub-pixel driving circuit; the sub-pixel driving circuit comprises a driving transistor and a compensation transistor; a first electrode of the compensation transistor is coupled to a second electrode of the driving transistor, and a second electrode of the compensation transistor is coupled to a gate of the driving transistor; the compensation transistor comprises an active layer and a gate; and the active layer of the compensation transistor comprises a channel part. The display substrate further comprises a pixel defining layer and a plurality of shielding patterns; at least some of the shielding patterns are located between the pixel defining layer and the gate of the compensation transistor; and an orthographic projection of the shielding patterns on the base at least partially overlaps with an orthographic projection of the channel part of the corresponding compensation transistor on the base.
