A metal mesh, comprising:

• at least two first metal lines which are in parallel with one another and separated from one another;
• and
• at least two second metal lines which are in parallel with and separated from one another, and intersect the at least two first metal lines,
• wherein the first metal lines and the second metal lines have a width of 1 μm-6 μm,
• wherein an intersection angle between the first metal lines and the second metal lines is 66 degrees-70 degrees,
• wherein a distance between two neighboring first metal lines and a distance between two neighboring second metal lines are 200 μm-210 μm,
• wherein the at least two first metal lines and the at least two second metal lines intersect to form at least one rhombus, and
• wherein the at least one rhombus has an acute angle between 66 degrees to 70 degrees, and the at least one rhombus has a height of 210 μm.
