Embodiment Construction

[0030] The technical solutions in the embodiments of the disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the disclosure. Apparently, the described embodiments are only some of the embodiments of the present disclosure, not all of them. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present disclosure.

[0031] Such as figure 1 as shown, figure 1 It is a schematic diagram of the structure of a liquid crystal display panel. A liquid crystal display panel is generally composed of a thin film transistor array substrate 100 , a color filter substrate 101 and a liquid crystal layer. The thin film transistor array substrate 100 is arranged opposite to the color filter substrate 101, and the liquid crystal layer is arranged between the thin film transistor array substrate 100 and the color f...

Abstract

The invention provides a display panel and a display device. The display panel comprises a first substrate and a second substrate. The second substrate comprises a display area and a packaging area located on the periphery of the display area. Frame glue is arranged on the second substrate, the first substrate is provided with at least one groove, a groove face of the groove is provided with a convex-concave structure, the groove is deeply filled with the frame glue, the contact area between film layers is increased through the convex-concave structure, the invasion path of water vapor is prolonged, and therefore the packaging effect of the frame glue is improved, and external water vapor is prevented from entering the display panel through the film layers.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display panel and a display device. Background technique [0002] In the field of display technology, liquid crystal display devices (Liquid Crystal Display, LCD) and organic electroluminescence display devices (Organic Light-Emitting Device, OLED) and other devices are widely used, and are constantly being applied in other fields. [0003] Taking a liquid crystal display panel as an example, the quality of the panel packaging will directly affect the service life of the panel. When the existing panel is packaged, sealant is usually coated on the package area on the first substrate, and then the first substrate, the device layer and the second substrate are aligned and pressed together, and finally the package of the panel is completed. For small-sized LCD panels, make corresponding grooves in the non-display area of ​​the panel to increase the filling amount of...
