Abstract

The embodiment of the present invention discloses a display panel, a manufacturing method thereof, and a display device. The display panel includes: a display substrate, the display substrate includes at least one display area; an encapsulation structure for encapsulating the display area, the encapsulation structure includes at least one inorganic layer and at least one organic layer, and the encapsulation structure is formed by first depositing each film layer and then etching. In the embodiment of the present invention, the packaging structure is formed by first depositing each film layer and then performing photolithography, so there is no need to use a mask to deposit the inorganic layer of the packaging structure, and it is not necessary to use a mask alignment system to align the mask. It reduces the complexity of the packaging process and the manufacturing cost; the thickness of the film layer of the packaging structure is uniform and the surface is flat, there will be no problem of uneven thickness in different regions caused by mask deposition, and the window effect of mask deposition is avoided.

Description

technical field

[0001] Embodiments of the present invention relate to display technologies, and in particular to a display panel, a manufacturing method thereof, and a display device. Background technique

[0002] With the development of display technology, the application of flexible display technology is becoming more and more extensive. The existing flexible organic light emitting display panel structure generally includes a flexible substrate, a display device layer, and a thin film encapsulation layer. The thin film encapsulation layer generally includes an inorganic layer and an organic layer, the inorganic layer is used to block water and oxygen, and the organic layer is used to improve the flexibility of the thin film encapsulation layer.

[0003] In a flexible organic light-emitting display panel, the inorganic layer of the thin film encapsulation layer is usually deposited after alignment using a mask mask. Specifically, before forming the thin film encapsulation...
