Abstract

Embodiments of the present invention provide a display panel and a display device, which relate to the field of display technology and are used to improve the bending resistance of the display panel, thereby improving the working stability of the display panel. The display area of ​​the display panel includes a plurality of pixel driving units, and each pixel driving unit includes a plurality of thin film transistors; the display panel also includes a gate metal layer, an inorganic layer and a source-drain metal layer arranged in layers; the gate electrode of the thin film transistor is located in the The gate metal layer; the source electrode and the drain electrode of the thin film transistor are located in the source and drain metal layer; the display area includes a bending area, the bending area has a bending axis, and in the bending area, the inorganic layer includes at least one groove, and the groove is connected to the bending area. The pixel driving units do not overlap. The above-mentioned display panel is used to realize screen display.

Description

【Technical field】 [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a display device. 【Background technique】 [0002] With the continuous development of display technology and the diversified demands of users for display devices, bendable and foldable display panels have been used more and more widely due to their advantages of foldability, portability, and wide application range. [0003] A plurality of metal signal lines are arranged in the display area of ​​the display panel, and an inorganic insulating layer is located between adjacent metal signal lines. However, for a display panel that can be bent and folded, as the number of bending times increases, the inorganic insulating layer may break, which in turn causes the metal signal lines near the inorganic insulating layer to break, which affects the normal operation of the display panel. [Content of the invention] [0004] In view of this, embodiments o...
