Abstract

The invention discloses a display panel, a manufacturing method thereof, and a display device, belonging to the technical field of display. The method includes: forming a flexible substrate; forming at least two barrier dams nested in a direction away from the display area on the non-display area of ​​the flexible substrate, and the first barrier dam closest to the display area among the at least two barrier dams is provided with A plurality of openings; an organic light-emitting element and a protective layer are sequentially formed on a flexible substrate formed with at least two barrier dams, the protective layer includes an organic film layer formed by a liquid organic material, and the liquid organic material is located in the area surrounded by the first barrier dam Internally, it solves the problem that the liquid organic material is easy to overflow over the barrier dam and affects the protective effect of the protective layer on the organic light-emitting element, resulting in a shortened service life of the organic light-emitting diode display device, and improves the protective effect of the protective layer on the organic light-emitting element. the life of the display device. The present invention is used in a display device.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] Compared with a liquid crystal display device, an organic light-emitting diode (English: Organic Light-Emitting Diode; abbreviation: OLED) display device has a self-luminous characteristic and does not require an independent light source. And because the organic light emitting diode display device has characteristics such as low power consumption, high brightness and fast response speed, the organic light emitting diode display device has received more and more attention. In the display panel of the organic light emitting diode display device, a protective layer needs to be used to protect the organic light emitting elements formed on the flexible substrate, so as to block the external water and oxygen. The protective layer is manufactured by thin film encapsulation (Thi...
