Display panel, manufacturing method of display panel and display device

Abstract

The invention discloses a display panel, a manufacturing method of the display panel and a display device, and belongs to the technical field of display. The display panel comprises an array substrateand a packaging cover plate which are oppositely arranged, at least one target substrate is arranged in the array substrate and the packaging cover plate, and the target substrate is provided with adisplay area and a non-display area; a supporting structure is arranged in the non-display area, and the side, away from the display area, of the supporting structure is coplanar with one side face ofthe array substrate or the packaging cover plate; the supporting structure is obtained from a cutting supporting structure in a display mother board when the display mother board is cut along a cutting line to form the display panel; the orthographic projection of the cutting supporting structure on the target substrate covers the area where the cutting line is located, so that when the display mother board is cut, the display mother board is cut along the cutting supporting structure, the problem that the stress of the display mother board is uneven due to cutting of other areas is avoided,and the appearance and quality of the display panel are ensured.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] With the development of display technology, display panels formed by organic light emitting diodes (Organic Light Emitting Diode, OLED) have been widely used due to their characteristics of self-illumination, fast response and wide viewing angle. The luminescent material is easily affected by water or oxygen to produce oxidation reaction, so the display panel needs to be packaged when manufacturing the display panel. [0003] In the related art, cutting with glue is an effective technical means to realize a narrow frame. Therefore, when manufacturing the display panel, glass glue needs to be coated on the supporting area of ​​the display motherboard first, and the glass glue is irradiated with laser to make the glass glue harden. However, because the glass glue in the...

Problems solved by technology

[0004] The present invention provides a display panel, its manufacturing method, and a display device, which can solve the problem of uneven force on the display mother board in the cutting process due to the fact that the glass glue may not completely cover the cutting line area in the related art, and the display obtained after cutting. The problem that the panel may be damaged, the technical solution is as follows:
