Abstract: A method of measuring adhesive strength includes setting an evaluation time (te), fixing a substrate and an adhesive member to a measurement device, pulling the adhesive member fixed to the measurement device with a first measurement force (Fe1) for the evaluation time (te), pulling the adhesive member fixed to the measurement device is pulled with a second measurement force (Fe2), which is obtained by increasing the first measurement force (Fe1) by a preset amount, for the evaluation time (te), and determining a reference measurement force (Fes) which is a static force applied to the adhesive member when a distance by which a first portion of the adhesive member is detached from the substrate is equal to a preset distance (dt) is determined.

Abstract: A display device includes a substrate including a bending area, a flat area adjacent to the bending area, and first and second surfaces opposite to each other, a display unit corresponding to the flat area and on the first surface, a support layer which is on the second surface of the substrate, corresponds to the flat area, and is disconnected at the bending area to define an end portion closest to the bending area, and the substrate defining a groove in the bending area. The end portion of the support layer is bendable together with the substrate and includes a flat portion corresponding to the flat area of the substrate, and a bending portion corresponding to the bending area of the substrate. The substrate which is unbent disposes the bending portion having an acute angle of inclination with respect to the second surface of the substrate.
