Abstract: A metal mesh includes: first metal lines (11) and second metal lines (12) extending in crossed directions. The first metal lines (11) are arranged side by side in a first direction and extend in a second direction; the second metal lines (12) are arranged side by side in the first direction and extend in a third direction. Each first metal line (11) includes first sub-line segments sequentially connected together in the second direction, and each second metal line (12) includes second sub-line segments sequentially connected together in the third direction. Each first sub-line segment has a midpoint superposing with a midpoint of one of the second sub-line segments, the first and second sub-line segments having superposed midpoints form a crossed structure (10), and define two opposite first angles (θ1) and two opposite second angles (θ2). Each first angle (θ1) is not greater than each second angle (θ1).
