1. A method for manufacturing a display device, comprising the steps of
providing a display substrate having a display surface, wherein the display surface has a first surface curvature,
providing a cover having a cover surface, wherein the cover surface has a second surface curvature different from the first surface curvature,
providing a spacer having a first spacer surface and a second spacer surface, wherein the first spacer surface has a first spacer surface curvature being adapted to the first surface curvature of the display substrate and wherein the second spacer surface has a second spacer surface curvature being adapted to the second surface curvature of the cover surface,
attaching the spacer to the cover with an adhesive layer so that the second spacer surface faces the cover surface, and
attaching the spacer to the display substrate with an adhesive layer so that the first spacer surface faces the display surface.
