Title:
DISPLAY SUBSTRATE AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/092444
Kind Code:
A9
Abstract:
A display substrate and a display device, capable of solving the existing problem that water vapor enters the interior of a display substrate along a gap to cause a defect of forming continuously expanding black spots. The display substrate comprises: a base (101), and a blocking structure (200) located on the base (101) and provided in a non-display region (20); the display substrate further comprises: a first conductive layer (102), a second conductive layer (103), and an anode conductive layer (104) that are located on the base (101) and sequentially arranged along a direction away from the base (101); the first conductive layer (102) has a first boundary line (1021); the anode conductive layer (104) has a second boundary line (1041) substantially parallel to the extending direction of the first boundary line (1021); the second boundary line (1041) is located on the side of the first boundary line (1021) away from a display region (10); in a fan-out region (20a), the first conducive layer (102) is cut off, and the second conductive layer (102) is continuously arranged; and in a corner region (20b), the anode conductive layer (104) is cut off, and an orthographic projection of the blocking structure (200) on the base (101) at least partially covers orthographic projections of the first boundary line (1021) and the second boundary line (1041) on the base (101).
