Abstract

An organic light-emitting panel comprises a substrate, a planarization layer, a reflection layer and a bank layer. The substrate is provided with a display area and a peripheral area located beside the display area. The planarization layer is disposed on the substrate and has a groove. The reflection layer is arranged on the planarization layer, wherein the reflection layer is arranged along the side wall of the groove. The bank layer is disposed on the planarization layer, and the bank layer covers the groove and has a peripheral area slope in the peripheral area. The groove is adjacent to the peripheral area slope and closer to the display area than the peripheral area slope. The invention also provides a manufacturing method of the organic light-emitting panel.

Description

technical field [0001] The present invention relates to an electronic device, and in particular to an organic light-emitting panel. Background technique [0002] The organic light-emitting panel uses an organic light-emitting material as a light-emitting layer, which has good display effects such as high brightness, high luminous efficiency, and high contrast. Generally speaking, the organic luminescent material can be fabricated on the substrate by vapor deposition or inkjet, and the inkjet fabrication is more efficient. However, manufacturing organic light-emitting materials on the substrate by inkjet may cause other problems, so the organic light-emitting panel still needs to be further improved. Contents of the invention [0003] The invention provides an organic light-emitting panel with good quality. [0004] The invention also provides an organic light-emitting panel, which can improve the yield of the organic light-emitting panel under the same manufacturing proc...
