Abstract

The invention describes a display panel, its manufacturing method and display device. The display panel includes: a base substrate with a display area and a non-display area, the non-display area includes a first non-display area and a second non-display area; at least one barrier is included along the direction away from the display area, and the barrier is located in the first non-display area. In the display area, the first non-display area surrounds the display area, and the second non-display area surrounds the first non-display area; the display function layer is located on the base substrate, and the display function layer includes at least one inorganic insulating layer; the inorganic layer insulating layer is in the The second non-display area forms a groove; the barrier layer is located on the side of the display function layer away from the base substrate, and the barrier layer includes at least a first inorganic barrier layer; the first inorganic barrier layer at least partially covers the groove. The invention can prevent the crack diffusion and water and oxygen intrusion, and improves the reliability and service life of the display panel.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display is a self-luminous display. Compared with LCD (Liquid Crystal Display, Liquid Crystal Display), OLED display does not require a backlight source, so OLED display is thinner and lighter. In addition, OLED display is also Due to the advantages of high brightness, low power consumption, wide viewing angle, high response speed, and wide operating temperature range, it is increasingly used in various high-performance display fields. [0003] The lifetime of an OLED display depends on the selected organic material on the one hand, and on the packaging method of the device on the other hand. For organic electronic devices, especially OLEDs, water vapor and oxygen from the surrounding environment ...
