Title:
DISPLAY PANEL AND MANUFACTURING METHOD THEREFOR, AND DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/142012
Kind Code:
A1
Abstract:
A display panel, comprising a base substrate (100). A display region (AA) of the display panel comprises a plurality of sub-pixel regions, and each sub-pixel region comprises a first pixel electrode (E1) located on the base substrate (100) and a second pixel electrode (E2) located on the side of the first pixel electrode (E1) facing away from the base substrate (100). The display panel further comprises an auxiliary electrode connection region; the auxiliary electrode connection region comprises an auxiliary electrode (107c) and an electrode connection structure which are located on the base substrate (100); the second pixel electrode (E2) is connected to the auxiliary electrode (107c) via the electrode connection structure; and an orthographic projection of the auxiliary electrode connection region on the base substrate (100) has no overlap with orthographic projections of the sub-pixel regions on the base substrate (100). The electrode connection structure comprises a first connection electrode (CE1) located on the auxiliary electrode (107c), a second connection electrode (CE2) located on the side of the first connection electrode (CE1) facing away from the base substrate (100), and a third connection electrode (CE3) located between the first connection electrode (CE1) and the second connection electrode (CE2); the third connection electrode (CE3) comprises an upper surface in contact with the second connection electrode (CE2), a lower surface in contact with the first connection electrode (CE1) and opposite to the upper surface, and a longitudinal section perpendicular to the upper surface or the lower surface; the longitudinal section comprises a top edge located in the upper surface and a bottom edge located in the lower surface; and an orthographic projection of the bottom edge on the base substrate (100) covers an orthographic projection of the top edge on the base substrate (100).
