Abstract
A substrate and a display device are provided. A first film layer of the substrate is formed on a third film layer and patterned to form a target pattern. A second film layer is formed on the third film layer and the first film layer. Within a distribution area of the target pattern, film edges of the first film layer are formed with protrusion structures facing the second film layer. Based on the protrusion structures, a deformable margin of the first film layer and the second film layer at a stacking position is increased, and a pattern of the second film layer is thus prevented from being cracked to generate cracks.
Claims20
A substrate, comprising:
- a first film layer;
- a second film layer;
- a third film layer;
- wherein the first film layer is formed on the third film layer, and patterned to form a target pattern;
- wherein the second film layer is formed on the third film layer and the first film layer, and the second film layer is stacked on the first film layer on edges of a distribution area of the target pattern;
- wherein a film shrinkage rate of the second film layer is less than a film shrinkage rate of the first film layer, and film edges of the first film layer are formed with protrusion structures facing the second film layer within the distribution area of the target pattern;
- wherein the first film layer is formed with at least three of the protrusion structures within the distribution area of the target pattern;
- and
- wherein a distance between two of the protrusion structures adjacent to each other is at least three times greater than a width of the protrusion structure.
A display device, including:
- a display panel, a substrate of the display panel including:
- a first film layer;
