DISPLAY DEVICE AND BASE MATERIAL LAMINATED BODY

WIPO Patent Application WO/2021/066191

A1

This display device is bendable and has a laminated structure including an optical film member, a first adhesive layer, a window member laminated on one surface of the optical film member with the first adhesive layer therebetween, a second adhesive layer, and a panel member laminated on the other surface of the optical film member with the second adhesive layer therebetween, the display device being characterized in that: the window member has a hard coating layer on a surface on the side opposite to the first adhesive layer; the laminated structure forms a thin film sealing layer on a surface of the panel member on the second adhesive layer side; a touch sensor member is laminated on a surface on a side of the thin film sealing layer opposite to the panel member with a third adhesive layer therebetween; a transparent conductive layer is formed on a surface on a side of the touch sensor member opposite to the panel member; the transparent conductive layer is easier to be broken than the window member and the optical film member when being bendingly deformed; and the values of the elongations of the transparent conductive layer, the thin film sealing layer, and the hard coating layer when being bendingly deformed are limited to be less than those of the respective breaking elongations, by establishing relationships of 0.8
