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 display panel including a display area and a non-display area, a window disposed on the display panel and including a base substrate and a printed layer disposed on a surface of the base substrate and overlapping with the non-display area, and an adhesive layer disposed between the display panel and the window. The adhesive layer includes a first adhesive portion overlapping with the non-display area, and a second adhesive portion adjacent to the first adhesive portion and having a creep value different from a creep value of the first adhesive portion.
