Method of adjusting display size

A method of adjusting a display size, comprising steps of:

• providing a display, and the display comprises a first substrate, a second substrate and an image generating medium sealed by a first seal part and a second seal part between the first substrate and the second substrate;
• locating a first cutting line on the first substrate between the first seal part and the second seal part, and locating a second cutting line on the second substrate between the first seal part and the second seal part, and an orthographic projection of the first cutting line on the second substrate does not overlap with the second cutting line;
• cutting the first substrate and the image generating medium along the first cutting line to form a first reservation part and a part of the image generating medium corresponding to the first reservation part, and cutting the second substrate along the second cutting line to form a second reservation part stacked with the first reservation part, and an edge of the first reservation part at the first cutting line contract inwardly relative to an edge of the second reservation part at the second cutting line to form a protruding part at the edge of the second reservation part;
• adding adhesive on a surface of the protruding part facing the first reservation part to make the adhesive permeate between the first reservation part and the second reservation part;
• and
• solidifying the adhesive.
