ABSTRACT:
A method of manufacturing a display device for displaying the function of a switch or the like. A body is formed with a cavity, and a sheet bearing a display is then positioned in the bottom cavity. The cavity is then filled with a transparent synthetic epoxy resin with a poly-oxy-propylene-amine for curing. Preferably a small amount of the material is placed on the bottom of the cavity before the display sheet is installed in order to secure the sheet to the bottom and prevent it from warping after the remaining resin is added.
