Abstract

The invention describes a display panel and a display device. The display panel comprises a substrate, a display function layer, a thin film encapsulation layer, at least one retaining wall and at least one groove, wherein the substrate is provided with a display area and a non-display area; the display function layer is located on the substrate, and the display function layer comprises at least one inorganic insulating layer; the thin film encapsulation layer is located on one side of the display function layer away from the substrate, and the thin film encapsulation layer comprises at leastone organic layer and at least one inorganic layer; the at least one retaining wall is located in the non-display area and on the same side as the display function layer, and the inorganic layer at least covers the retaining wall; the at least one groove is located on one side of the inorganic insulating layer away from the substrate and is arranged in the non-display area between the retaining wall and the display area, the groove accommodates the organic layer, the vertical projection of the groove on the substrate has different widths in the first direction, and the first direction is a direction that the display area points to the non-display area. According to the scheme of the invention, the risk of disconnection caused by forming touch electrode lines on the retaining wall and the risk of cracking caused by film layer peeling can be reduced, and the reliability of encapsulation can be improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel 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. However, since the OLED device will be corroded and damaged under the action of water vapor and oxygen, it is particularly important to select a better packaging method for the OLED device. [0003] At present, thin-film encapsulation is a widely used encapsulation method in the manufacture of OLED...
