  • Publication number: 20230408884
    Abstract: Thicknesses of a light control layer measured in multiple measurement positions are within the range of 0.8 times to 1.2 times the median value of the thicknesses. In a characteristic curve obtained by measuring a change in haze when a drive voltage applied to transparent electrode layers is changed, a first voltage is a lower limit drive voltage in the range in which the change ratio in haze is 0.5%/V or more, a second voltage is the upper limit drive voltage, and the middle value is a value between the first voltage and the second voltage. The variance in the middle value is 40% or less, in which the variance is obtained by dividing a difference between the minimum value and the maximum value, among middle values obtained from the characteristic curves in multiple measurement positions, by an average value of the middle values.
