Abstract

The embodiment of the invention provides a display panel and a display device, and relates to the technical field of display. The display panel is used for improving the bending performance of storagecapacitors, thereby improving the working stability of the display panel; the display panel comprises a substrate, wherein a display area of the substrate is provided with a plurality of sub pixels,each sub pixel comprises a pixel circuit and a light-emitting component; each pixel circuit comprises a thin film transistor and a storage capacitor, and each storage capacitor comprises a first electrode plate and a second electrode plate which are arranged oppositely; the display area comprises a bending area, the bending area is provided with a bending shaft, the included angle between the extending direction of at least one edge of the first electrode plates and / or second electrode plates of the storage capacitors in the bending area and the extending direction of the bending shaft is alpha, and alpha is less than or equal to 30 degrees. The display panel is used for achieving image display.

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] With the continuous development of display technology and the diversified demands of users on display devices, bendable and foldable display panels have been more and more widely used. [0003] A plurality of pixel circuits are provided in the display area of ​​the display panel, and each pixel circuit includes a storage capacitor. Generally speaking, the storage capacitor is composed of two metal plates oppositely arranged in a shape of a rectangle. However, for a bendable and foldable display panel, as the number of bending increases, the metal plate of the storage capacitor may break, causing the capacitance value of the storage capacitor to deviate from the standard value. A short circuit occurs, affecting the normal operation of the display panel. 【Content of invention】 [0004] In view of t...
