Abstract

The embodiment of the invention provides an organic light emitting display panel and a manufacturing method thereof. The organic light emitting display panel comprises a display area, a through hole area and a through hole boundary area. The display area at least partially surrounds the through hole area, and the through hole boundary area is located between the display area and the through hole area. The organic light emitting display panel includes a base substrate; a group including a reflective electrode, an organic light emitting structure, and an opposite electrode which are stacked on the base substrate and are located at least in the display area; and a segment portion located on the same side of the base substrate as the organic light emitting structure and located in the throughhole boundary area. A side of the segment portion adjacent to the display area and a side of the segment portion away from the display area have grooves. The organic light emitting structure and the opposite electrode extend from the display area to the through hole boundary area, and are segmented into portions that are not connected to each other by the segment portion. The embodiment of the present invention provides an organic light emitting display panel and a manufacturing method thereof to improve a water oxygen isolation effect.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting display panel and a manufacturing method thereof. Background technique [0002] Liquid crystal display devices or plasma display devices have limitations in developing self-luminous elements with high flexibility and elasticity, and thus there are limitations in using them as flexible display devices. In contrast, an organic light emitting display device is formed using an organic thin film known as an optimum material that can be applied to a flexible display device by utilizing flexibility and elasticity, characteristics of an organic thin film. [0003] The organic light emitting display device may be deformed into various forms as its application fields are diversified. As part of this, an opening penetrating the inside of the organic light emitting display device needs to be processed. When openings are provided, it is difficult for an organic li...
