A daylighting device according to an aspect of the invention includes at least a daylighting film that includes a base having optical transparency and daylighting portions having optical transparency and provided on one surface of the base. Each of the daylighting portions has a reflective surface by which light incident on the daylighting portion is reflected and the light reflected by the reflective surface and output from a second surface of the base has a characteristic that the light travels toward a space on a side where the light is incident on the reflective surface, the space being one of two spaces divided by a virtual plane as a boundary which is vertical to the second surface of the first substrate and parallel to a direction of the daylighting portion extending, and intervals s between adjacent daylighting portions are set to various values.

Daylighting device, molding die, and method of manufacturing daylighting film

Provided is a daylighting film () including: a base () having light-transmissive performance; a plurality of first protrusion portions () that have light-transmissive performance and are provided to be adjacent to each other on one surface () of the base (); a gap portion () provided between the first protrusion portions (); and at least one second protrusion portion () that is provided in at least one gap portion () to be adjacent to the first protrusion portions () on the one surface () of the base () and that is formed of the same material as that of the first protrusion portions (), in which a height of the second protrusion portion () from the one surface () of the base () is smaller than a height of each of the first protrusion portions () from the one surface () of the base ().

Daylighting film, die for forming daylighting film, and manufacturing method for daylighting film

A liquid crystal display device of one aspect of the present invention includes a liquid crystal display unit that includes a liquid crystal layer which exhibits vertical alignment and plural picture elements, and a control unit that controls a voltage which is supplied to the liquid crystal display unit. The control unit performs display by sequentially applying a first voltage that corresponds to a larger gradation number than an original gradation number and a second voltage that corresponds to zero gradation respectively in plural subframe periods that result from division of one frame period of an image signal in a case where the original gradation number of the input image signal is a low gradation number that is less than a prescribed threshold value, performs display by applying the second voltage in the one frame period in a case where the original gradation number is the zero gradation, and performs display by applying a third voltage that corresponds to the original gradation number in the one frame period in a case where the original gradation number is a high gradation number that is equivalent to or more than the threshold value.

Liquid crystal display device reducing color shift

A daylighting apparatus of the present invention includes: a daylighting sheet () that has first and second surfaces opposite to each other and that lets light in through the first surface and lets the light out through the second surface at a predetermined distribution of angles; and a visible light-reflecting sheet () that reflects part of visible light falling on the first surface of the daylighting sheet ().

Daylighting apparatus

A daylighting system () to be installed over an interior face () of a window pane (), the daylighting system () including: a light-transmitting device () to be disposed over an upper part of the interior face () of the window pane (); and a shading device () joined to the light-transmitting device () in such a manner as to be disposed over a lower part of the interior face () of the window pane ().

Daylighting system

There is provided a daylighting device () installed to face window glass and including a daylighting member () having a light-transmissive base member and a plurality of light-transmissive daylighting units disposed adjacent to each other on at least one surface of the base member, and the daylighting member () includes a movable unit that moves such that the one surface of the base member follows a movement of the sun to turn toward an orientation of the sun.

Daylighting device and daylighting system

A daylighting film () according to an aspect of the invention includes a first base (), a plurality of daylighting portions () constituted by a plurality of polygonal prism structures, and gaps () provided between the plurality of daylighting portions (). Each of the daylighting portions () is a polygon that has four vertexes in a sectional shape orthogonal to a longitudinal direction and has all interior angles less than 180&#xb0;, and has a first side that is a side of the polygon corresponding to a surface in contact with the first base () and a plurality of vertexes including a first vertex and a second vertex that are vertexes corresponding to both ends of the first side, and a third vertex that is not positioned on the first side. A length of a line perpendicular to the first side passing the third vertex is longer than lengths of lines perpendicular to the first side passing vertexes other than the third vertex among the plurality of vertexes, and a shape of the daylighting portionis asymmetrical with the line perpendicular to the first side passing the third vertex as a center.

Daylighting member, daylighting device, and installation method for daylighting member

A daylighting device of the present invention includes: a daylighting member including: a first light-transmitting base member; and a plurality of protruding, light-transmitting daylighting sections provided on a first face or a second face of the first light-transmitting base member; and a ventilation hole configured to enable a space on the first face to communicate with a space on the second face opposite from the first face.

Daylighting device

A daylighting device () according to an aspect of the present invention includes a first substrate () which has optical transparency and to which external light is incident; a second substrate () which has optical transparency and is disposed facing the first substrate (); a light diffusion layer () which is disposed between the first substrate () and the second substrate (); and a daylighting layer () which is disposed between the first substrate () and the second substrate () and is formed by including a plurality of daylighting portions () having optical transparency and a void portion () which is provided between the plurality of daylighting portions () in one surface facing the light diffusion layer ().
