Abstract: In a display manufacturing method including bonding of a light-transmissive substrate onto a display surface of a display body, the bonding includes bending the light-transmissive substrate into an arch-like shape with a bonding surface thereof having a convex shape. An adhesive sandwiched is put between a bonding surface of the display body and a top of a bonding surface of the bent light-transmissive substrate. The bend of the light-transmissive substrate is released while moving two rollers from a center of the light-transmissive substrate in a direction of the bend of the light-transmissive substrate towards both terminal edges of the light-transmissive substrate in mutually reverse directions. The two rollers press a non-bonding surface of the light-transmissive substrate against the display body.

Abstract: A method for manufacturing a display, where the display includes a light-transmissive substrate adhering to a display substrate that forms a display surface side of a display body. An edge of at least either an adhesion surface of the display substrate or an adhesion surface of the light-transmissive substrate is coated with an adhesive. The display substrate and the light-transmissive substrate are positioned in an offset manner to provide overlapping and non overlapping regions. For example, an edge of each of two adhesion surfaces overlap with each other, and other regions do not overlap with each other. The display substrate and the light-transmissive substrate are relatively moved to a position where an edge of the display substrate and an edge of the light-transmissive substrate respectively overlap with other edges in a state in which adhesive reservoirs are formed while maintaining a fixed gap between the two adhesion surfaces.
