Title:
DISPLAY SUBSTRATE AND MANUFACTURING METHOD THEREFOR, AND DISPLAY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/205083
Kind Code:
A1
Abstract:
A display substrate and a manufacturing method therefor, and a display apparatus. The display substrate comprises: a base substrate, an organic light emitting element located on the base substrate, a data line, and an electrode line. The organic light emitting element comprises a first electrode, a light emitting layer, and a second electrode sequentially stacked in a direction perpendicular to the base substrate. The second electrode is located on the side of the light emitting layer facing the base substrate. The data line is located between the base substrate and the organic light emitting element, and extends in a first direction. The electrode line and the data line are arranged in a same layer and located in a region outside a light emitting region of the organic light emitting element. The display substrate further comprises at least one connection portion located in the region outside the light emitting region and configured to connect the electrode line and the first electrode. The connection portion is spaced apart from the second electrode. The light emitting layer covers the second electrode and the at least one connection portion. Embodiments of the present disclosure can effectively reduce the resistance of the first electrode by providing the connection portion in the display substrate to connect the electrode line and the first electrode of the organic light emitting element.
