Abstract: A lighting device includes light sources arranged in an arrangement direction, a first light guide plate, and a second light guide plate on the first light guide plate. The first light guide plate includes a first light entering surface, a first light exit surface, and a first light diffusion portion adding a diffusion action to light to be refracted and travel in a crossing direction crossing the arrangement direction. The second light guide plate includes a second light entering surface, a second light exit surface, and a second light diffusion portion adding a diffusion action to light to be refracted and travel in the arrangement direction seen from the normal direction of the second light exit surface. The second light diffusion portion includes first lenses that include ridgelines extending in the crossing direction and inclined portions inclined at an angle from 35° to 55° inclusive relative to the normal direction.

Abstract: Provided is a holding manner determination device that accurately determines a manner of holding an information terminal. A matching processing unit (312) calculates a coincidence between distribution data of sensor values detected by a touch panel (10) and holding hand reference data (Ref1), and a holding hand determination unit (314) determines a holding hand on the basis of holding hand information of the holding hand reference data (Ref1) whose coincidence with detection data is equal to or greater than a threshold.

Abstract: A lighting device includes a mounting substrate comprising a first pair of conductive pads and a second pair of conductive pads arranged along a first direction on the mounting substrate. The first pair of conductive pads is offset from the second pair of conductive pads in the first direction and a second direction intersecting the first direction with respect to a plane parallel to the mounting substrate. A first light emitting device is coupled to the first pair of conductive pads, and configured to emit lights toward a first side within a space formed between the mounting substrate and a diffusion plate. A second light emitting device is coupled to the second pair of conductive pads, and configured to emit lights toward a second side opposite of the first side within the space formed between the substrate and the diffusion plate.

Abstract: A reflection sheet stacked on a mounting surface of a light source substrate on which light sources are mounted includes an insulating sheet and a reflection layer. The insulating sheet is made of an insulating material. The reflection layer includes a metal thin film stacked on the insulating sheet. Holes are drilled through the reflection layer and the insulating sheet in a stacking direction in which the reflection layer is stacked on the insulating sheet so that the light sources are exposed therethrough. The reflection layer is divided into divided reflection areas by slits. The holes are formed in the divided reflection areas, respectively.
