Abstract: A transparent substrate for a liquid crystal device includes an alignment layer that regulates an alignment direction of liquid crystal molecules contained in a light control layer included in a light control sheet, which is the liquid crystal device, and a base layer on which the alignment layer is formed. The substrate includes a first surface and a second surface opposite to the first surface. The first surface is part of the alignment layer. The second surface is part of the base layer. A surface, which contacts the alignment layer, of the base layer has surface roughness Ra1 of 20 nm or less in a pencil hardness test. A sum Ra1+Ra2 of the surface roughness Ra1 and surface roughness Ra2 of the second surface is 5 nm or more.

Abstract: A range imaging device includes a light source unit that emits light pulses to a measurement space; a light-receiving unit including a photoelectric conversion element that generates charge according to light incident from the space, a pixel circuit including charge storage units in which the charge is integrated in a frame cycle, and a pixel drive circuit that performs switching operation of transfer transistors to distribute the charge to the storage units for integration at integration timing synchronizing with emission of the pulses; and a distance calculation unit that calculates a distance between object in the space and the light-receiving unit based on charge determined by a first charge integrated in each storage unit. The calculation unit calculates the distance by subtracting a second charge from each first charge, the second charge being noise charge as an integrated charge other than the charge distributed and integrated by the switching operation.
