Abstract

The invention relates to the field of display and technology, and mainly relates to a display device, a display panel and a manufacturing method thereof. The display panel comprises a driving backboard and a stress absorption layer, the driving backboard comprises a pixel circuit area and a peripheral area located outside the pixel circuit area, the peripheral area comprises a bending area, the bending area and the pixel circuit area are sequentially distributed in the first direction, the bending area comprises a plurality of isolation grooves distributed at intervals in the second direction, the second direction intersects with the first direction, and the isolation grooves penetrate through the driving backboard; and the stress absorption layer is arranged in the bending area and comprises a plurality of absorption parts, and the absorption parts and the isolation grooves are alternately distributed in the second direction. According to the display panel, the narrow frame design can be realized, and the product yield is improved.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular, to a display device, a display panel and a manufacturing method thereof. Background technique [0002] With the development of display technology, flexible display panels (Organic Light Emitting Diode, OLED for short) are widely used in display technology due to their advantages of thinness, high contrast, flexibility, and short response time. Existing flexible display panels mainly include a display area and a peripheral circuit area. In order to achieve a narrow frame design, it is usually necessary to bend the peripheral circuit area to the back of the display area. However, when bending, the bending area is prone to breakage, and the product yield is low. [0003] It should be noted that the information disclosed in the above background section is only for enhancing the understanding of the background of the present disclosure, and therefore may include informati...
