Abstract

The embodiment of the invention provides a display panel and a display device, which relates to the technical field of display and used for improving the bending reliability of each film layer in a bending area of the display panel. The display panel comprises a flexible substrate, a light emitting device and a support layer, wherein the flexible substrate includes a display area and a bending area which are arranged in the first direction; the bending area includes a first edge and a second edge which are arranged in the second direction; the first direction interests with the second direction; the bending area includes a bending axis, and the bending axis extends in the second direction; the light emitting device is located in the display area; the support layer and the light emitting device are located at the same side of the flexible substrate; the support layer includes a first support layer, the first support layer is overlapped with the bending area, and the first support layercovers the first edge; and the minimum distance from the first support layer to the second edge in the second direction is greater than zero.

Description

[0001] 【Technical field】 [0002] The present invention relates to the field of display technology, in particular to a display panel and a display device. [0003] 【Background technique】 [0004] With the continuous development of display technology, the requirements for the appearance size of the display screen are getting higher and higher. Especially for mobile display products such as mobile phones, it is more required to have a display effect with narrow borders and high screen-to-body ratio, that is, it is expected that the size of the non-display area around the display area of ​​the display panel will be smaller and smaller. [0005] In order to increase the screen-to-body ratio of the display panel, the driver chip that drives the display panel for display is usually bound to a bendable flexible substrate, and then the flexible substrate bound with the driver chip is bent to the display panel. The backlight side is used to increase the screen-to-body ratio of the disp...
