Masks and display devices

A mask comprising:

• an evaporation surface;
• and
• a glass surface facing away from the evaporation surface, the mask being provided with a plurality of evaporation holes distributed in an array, the evaporation holes penetrating the evaporation surface and the glass surface, the evaporation holes comprising a first opening on the evaporation surface and a second opening on the glass surface, an orthographic projection of the first opening on the glass surface being a first projection opening covering the second opening;
• wherein:
• an interval between the first projection opening and the second opening in a first direction of tensioning the mask is a first interval, an interval between the first projection opening and the second opening in a second direction perpendicular to the first direction being a second interval;
• the plurality of evaporation holes is distributed in a plurality of rows, the second interval of the evaporation hole in even rows being less than the first interval, the second interval of the evaporation hole in odd rows being equal to the first interval;
• or
• the second interval of the evaporation hole in even rows is equal to the first interval, and the second interval of the evaporation hole in odd rows being less than the first interval.
