Abstract: A flexible image display device includes a window member, a first member, a first laminate or a first touch-sensor-equipped panel member, and a plurality layers of tacky members. The first laminate is a laminate of a second member and a member 3A (including a panel member). When the first laminate is included, one of the first and second members is an optical film, and the other is an optical film or a touch sensor. The plurality layers of tacky members at least include three layers each disposed between the members. When the first touch-sensor-equipped panel member is included, the first member is an optical film, and the plurality layers of tacky members at least include two layers each disposed between the members. E0×T0≤0.32 (E0: elastic modulus (GPa) of the window member, T0: thickness (mm) of the window member).

Abstract: A water vapor concentration in a test gas in a first space of a measurement space in which a sample is disposed is adjusted, and a water vapor concentration m a earlier gas in a second space separated from the first space by the sample is measured by a measurement unit. When the water vapor concentration in the test gas is changed, a shift B in charge of the water vapor concentration in the carrier gas from the change of the water vapor concentration in the test gas is calculated. The calculated shift B in the change of the water vapor concentration in the carrier gas corresponds to ease of moisture accumulation in the sample. Thus, it is possible to analyze not only the amount of moisture permeating the sample but also the ease of moisture accumulation, so that characteristics of the sample can be widely analyzed.

Abstract: A water vapor concentration in a test gas in a measurement chamber in which a sample is disposed is adjusted, and a moisture amount of the sample in the measurement chamber is measured by a measurement unit. When the water vapor concentration in the test gas in the measurement chamber is changed, a shift B in change of the moisture amount of the sample measured by the measurement unit, from change of the water vapor concentration in the test gas, is calculated. The calculated shift B in the change of the moisture amount of the sample corresponds to an adsorption-desorption rate of the sample. Thus, it is possible to analyze not only the moisture amount of the sample but also the adsorption-desorption rate of the sample, so that characteristics of the sample can be widely analyzed.
