    Abstract: A light control sheet includes transparent electrode layers including first and second transparent electrode layers, a light control layer formed between the first and second transparent electrode layers, a first transparent support layer formed on the first transparent electrode layer on the opposite side of the light control layer, and a second transparent support layer formed on the second transparent electrode layer on the opposite side of the light control layer. The first transparent support layer has a support surface supporting the first transparent electrode layer, and the first transparent electrode layer includes a first electrode element and a second electrode element such that the first and second electrode elements are formed along the support surface and electrically insulated from each other by a groove extending along the support surface and having a depth passing through the first transparent electrode layer and not passing through the first transparent support layer.

    Abstract: A light control sheet includes a first characteristic and a second characteristic selectively exhibited. In the first characteristic, an absolute value of a change in clarity per unit voltage is greater than an absolute value of a change in haze per unit voltage. In the second characteristic, an absolute value of a change in haze per unit voltage is equal to or greater than an absolute value of a change in clarity per unit voltage. Haze is calculated in accordance with JIS K 7136:2000. Clarity is calculated by 100×(LC−LR)/(LC+LR). LC is an intensity of straight light travelling straight along a travelling direction of parallel light that has entered the light control sheet, and LR is an intensity of narrow-angle scattered light having an angle within ±2.5° relative to the travelling direction of the parallel light.

    Abstract: A light shielding plate includes a front surface located on a light incident side, a rear surface opposite to the front surface, and a hole passing through the light shielding plate between the front surface and the rear surface. The hole has a first hole portion and a second hole portion connected to the first hole portion at an intermediate opening thereof. The first hole portion extends from a rear surface opening on the rear surface to the intermediate opening and is shaped so as to taper from the rear surface toward the front surface. The second hole portion extends from a front surface opening on the front surface to the intermediate opening and is shaped so as to taper from the front surface toward the rear surface. The front surface opening is larger than the rear surface opening. The intermediate opening has a circularity of 3 μm or less.
