Claim 16:
17. 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 material of the first film layer is organic material, and material of the second film layer is inorganic material; and
wherein the substrate is a color filter substrate, the first film layer is a color filter layer and/or an organic planarization layer, and the second film layer is a transparent common electrode layer.
