Abstract

The invention discloses a display panel and a manufacturing method thereof, a protective film and a display device, comprising a display area, a non-display area and a bent area; A flexible substrate,a display layer and a bending protective layer, wherein the bending protective layer is located in a non-display area and the bending protective layer is at least partially located in the bending area; The bent protective layer includes an upper surface, a lower surface, and a side surface connecting the upper surface and the lower surface. In at least one first section, the length of the vertical projection of the sides on the flexible substrate is L, and the lengths of the upper and lower surfaces in a direction perpendicular to the display panel are D, wherein 0 <= L <= D / 10, the first section is perpendicular to the display panel and perpendicular to the edges of the cut display panel. The invention effectively avoids the circuit traces whose stress concentrates on the edge of the bending region when bending, so that the stress on the circuit traces in the display layer in the bending region is relatively uniform.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a manufacturing method thereof, a protective film, and a display device. Background technique [0002] The development of traditional flat panel display device technology has become increasingly mature. With the improvement of display technology, flexible display panels are gradually becoming popular. Existing flexible display panels are made of soft substrate materials, can be bent and rolled, and have the characteristics of low power consumption, small size, and various display methods. In recent years, they have become one of the hotspots in the field of flexible display research. [0003] In the existing flexible display panel, the substrate usually includes a display area and a non-display area surrounding the display area. The non-display area is provided with a flexible circuit board. integrated circuits. A metal wire is also arranged i...
