Abstract

Provided is a novel double-sided adhesive sheet for image display device which can be bonded to the adhesion surface in close contact without space therebetween although there is a step due to printing or the like on the adhesion surface to be bonded to the adhesive sheet. The double-sided adhesive sheet for image display deviceof the invention is a sheet to bond any two adherends selected from a surface protective panel, a touch panel, and an image display panel, and the sheet is characterized in that at least one of the adherends (surface protective panel) has a stepped portionon an adhesion surfaceto adhere to the double-sided adhesive sheetand the surface shape of the bonding surfaceof the double-sided adhesive sheetto be bonded to the adhesion surfaceis shaped in accordance with the surface shape of the adhesion surface
