Problems solved by technology

[0006] The above methods have a certain effect in reducing stress, but it is not conducive to maintaining the bending angle (R angle), and the performance of preventing external stress interference is low
In fact, due to insufficient bending process capability, external force interference, etc., the bending angle is not ideal, and the bending angle will be deformed inward, or the bending angle will be shifted to one side, which will cause cracks or breaks

Abstract

The invention provides a display panel and a manufacturing method of the display panel. The display panel is defined with a bending area and a non-bending area, and the display panel includes a substrate layer, an array layer, and a light emitting layer in sequence from bottom to top, wherein the substrate layer located in the bending area is far away from the array layer One side is provided with a first groove. The manufacturing method of the display panel includes: the step of manufacturing the substrate layer, the step of etching the substrate layer and the step of completing the manufacturing of the display panel. The invention can enhance the bending angle stability of the bending area, and avoid cracks or fractures caused by excessive local stress caused by its deformation.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a method for manufacturing the display panel. Background technique [0002] Active matrix organic light-emitting diode (AMOLED) display technology, compared with other traditional display technologies, has a series of advantages such as thinness, high contrast, low response time, and high color saturation, among which the bendable feature is its most prominent One of the advantages. [0003] Such as figure 1 As shown, it is a typical AMOLED display panel structure in the prior art, and a segmented protective film structure is adopted for the bending area in actual production. The display panel includes a protective film layer (usually a backplane) 1 , a flexible substrate layer 2 and an array layer 3 from bottom to top. The display panel is defined with a bending area 10 and a non-bending area 20. In order to facilitate bending, the protective film layer 1 of th...
