  • Patent number: 11743445
    Abstract: To provide a naked-eye type stereoscopic display device which can achieve a fine stereoscopic display property while achieving high-definition display and high yield. An aperture part includes overlapping regions which overlap with an aperture part or another aperture part neighboring to each other in a second direction and a non-overlapping region which does not overlap. Provided that a light amount emitted from a linear aperture of the aperture part in parallel to a second direction is “longitudinal light amount”, the non-overlapping region includes longitudinal light amount fluctuating regions where the longitudinal light amount changes continuously from roughly a center of the aperture part towards both ends of the first direction, respectively. The sum of the longitudinal light amounts of the two overlapping regions overlapping with each other at a same position in the first direction is larger than the longitudinal light amount in roughly the center of the aperture part.

  • Patent number: 11585795
    Abstract: An optical detection type chemical sensor includes a light source, a detection element and a photodetector. The detection element is constituted of a laminate in which a multilayer film including a chemical detection layer, an optical interference layer, and a half mirror layer is formed on a transparent substrate. At least one of the layers includes a magnetic material. Light from the light source is applied to the detection element under the condition that the light enters inside of the detection element from the rear surface of the transparent substrate on which the laminate is not formed and multiple reflection occurring in the laminate intensifies the magneto-optical effect. A subject is detected by using the photodetector to detect a magneto-optical signal indicating a change in reflected light from the laminate resulting from a change in an optical property resulting from a reaction in the chemical detection layer.
