Document Type and Number:
WIPO Patent Application WO/2022/133781
Kind Code:
A1
Abstract:
A display substrate (100) and a display apparatus. The display substrate (100) comprises a display area (AA) and a peripheral area surrounding the display area (AA), the peripheral area comprising a first edge (102) extending in a first direction, a second edge (103) extending in a second direction, and a transition edge (104) located between the first edge (102) and the second edge (103); and the display substrate (100) comprises a base (201) and an encapsulation layer (202) located on the base (201), and the display substrate (100) further comprises a plurality of via holes, wherein the via holes are located between the base (201) and the encapsulation layer (202), the via holes comprise a first via hole located at the transition edge (104), the first via hole comprises a first target via hole, the cross section of the first target via hole in a direction parallel to the base (201) is elongated, and the lengthwise direction of the first target via hole intersects both the first direction and the second direction. The via hole is equivalent to a flow guide groove, so that the material of the encapsulation layer (202) can flow to a certain extent in a direction along the extension direction of the via hole to a direction close to the transition edge (104), thereby facilitating improving the material fluidity of the encapsulation layer (202), and facilitating improving the reliability of the display substrate (100).
