Abstract

The embodiment of the invention provides a display panel and a display device, relates to the technical field of display, and effectively reduces the risk that a metal circuit is broken in a bending area. The display panel comprises a flexible substrate which comprises a display area and a non-display area, the non-display area comprises a bending area and a non-bending area, and the bending area is provided with a bending axis; a display layer which is located on one side of the flexible substrate and located in the display area and the non-display area, and the display layer comprises a first metal layer located in the bending area; a neutral surface adjusting layer which is positioned on one side, back to the flexible substrate, of the first metal layer, wherein the bending area comprises a first bending area and a second bending area, the bending shaft is located in the first bending area, and the neutral surface adjusting layer is only located in the first bending area.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device. 【Background technique】 [0002] In order to further increase the screen-to-body ratio of the display device, the substrate of the display panel is usually set as a flexible substrate. During the process of the display device, the driver chip is bound to the bendable side of the flexible substrate, and then the The flexible substrate is bent so that the driver chip is placed on the backlight side of the display panel. [0003] However, metal circuits are disposed in the bending region of the flexible substrate, and during the bending process, this part of the metal circuits is prone to breakage under stress, resulting in reduced reliability of the display device. 【Content of invention】 [0004] In view of this, the embodiments of the present invention provide a display panel and a display device, which can effectively reduce the ...
