Abstract

The invention provides a display panel, a manufacturing method and a display device. The display panel includes a flexible substrate and a display device, and the display device is located on one side of the flexible substrate; the flexible substrate includes a bent zone, the bending zone includes a bending axis extending along a first direction; the bending zone includes a first area and a second area, and along the first direction, the second area is located in the first area On both sides, wherein, the average thickness of the flexible substrate in the first region is greater than the average thickness of the flexible substrate in the second region. By locally thinning the edge of the flexible substrate substrate, the risk of cracks during the bending process is reduced, and the bending reliability of the display panel is improved.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel, a manufacturing method of the display panel and a display device including the display panel. Background technique [0002] The development of traditional flat panel display device technology has become increasingly mature, and flexible display devices have become the mainstream in the display field due to their thinness, bendability, and impact resistance. Among the display technologies that can realize flexible display at present, OLED (Organic Light Emitting Display, organic light-emitting diode display) has excellent performances such as fast response speed, wide viewing angle, high brightness, low power consumption, etc. , in recent years, has become a research hotspot in the field of flexible display. [0003] Flexible display panels are prone to cracks during bending. However, OLED devices are very sensitive to water vapor and oxygen, and are prone to attenua...
