Japanese Patent JP2021071713
Kind Code:
A
Abstract:
To provide an optical laminate device with superior flexibility and shock resistance, and a display device.SOLUTION: An optical laminate provided herein comprises a front plate, a third adhesive layer, a protective film, a second adhesive layer, a polarizing layer, a first adhesive layer, and a touch sensor layer arranged in the described order from the viewer side, and has a shock resistance index A of 200 or greater, as expressed by a formula 1 below. [In the formula, tn represents a thickness (μm) of the n-th adhesive layer from the touch sensor layer, G'n represents a storage modulus (MPa) of the n-th adhesive layer from the touch sensor layer at 25°C, and an represents a value obtained by dividing a distance (μm) from an upper surface of the touch sensor layer to a bottom surface of the n-th adhesive layer by tn.SELECTED DRAWING: Figure 1
