The present invention aims to provide an interlayer film for laminated glass capable of displaying images with a high luminous intensity when irradiated with a light beam and having excellent durability, and a laminated glass including the interlayer film for laminated glass. The present invention relates to an interlayer film for laminated glass, including a light-emitting layer that contains a polyvinyl acetal resin and a lanthanoid complex as light-emitting particles, the light-emitting layer containing not more than 100 ppm in total of a nitric acid-derived component and a carbonate component.

Laminated glass suitable as an optical combiner for HUD is obtained by laminating at least one insert A comprising polyvinyl acetal PA and optionally at least one plasticiser WA and at least one film B comprising polyvinyl acetal PB and at least one plasticiser WB between two glass sheets, wherein prior to lamination the amount of plasticiser WB in film B is at least 24% by weight, and insert A has a non-uniform thickness profile over at least one direction of its surface.

A glazing for information display includes an assembly of two transparent inorganic or plastic sheets, connected together by a thermoplastic or adhesive interlayer or by multilayer sheets incorporating the interlayer, wherein a luminophore material is incorporated to enable the display. One of the luminophores includes a benzene ring substituted at least by: a first ester COOR group, wherein R is a linear or branched carbon-based group including a main carbon-based chain of at least six consecutive carbon atoms, the R group including, if the chain is linear, more than 10 carbon atoms and, if the chain is branched, at least 7 carbon atoms, optionally a second COOR group, wherein R is another hydrocarbon-based group or hydrogen, the second group optionally being in para position on the benzene ring with respect to the first ester group, two hydroxyl OH groups that are optionally in para position on the benzene ring.

The present invention aims to provide a luminescent sheet capable of displaying high-luminance images under irradiation with light and capable of controlling the adhesion to glass, and an interlayer film for a laminated glass and a laminated glass each including the luminescent sheet. Provided is a luminescent sheet including: a thermoplastic resin; a luminescent material; and a cyclic coordination metal compound having a five- or more-membered ring structure formed by coordinating an organic compound having in a molecule two or more atoms of at least one kind selected from oxygen, phosphor, nitrogen, and sulfur, to at least one metal selected from an alkali metal, an alkaline earth metal, and magnesium.

A fluorescent display suitable for use in a heads up display contains a laminated glass structure containing a plasticized polyvinyl acetal film, at least one fluorophore, and at least one UV absorber, wherein the fluorophore and UV absorber are and remain spatially separated in the laminating film such that UV light projected from a display generating projector remains able to activate the fluorophores, and a UV component of sunlight has lessened ability to activate the fluorophore.

The present invention aims to provide a display device capable of displaying a gradation pattern in which the gradation pattern on a laminated glass can be changed at will and a display state can be switched to a transparent state, and an automobile roof glass and a building window glass each including the display device. Provided is a display device capable of displaying a gradation pattern, including: a laminated glass including a pair of glass plates and an interlayer film for a laminated glass that contains a thermoplastic resin and a luminescent material and is interposed between the pair of glass plates; and a light source configured to emit light of excitation wavelength for the luminescent material, the laminated glass and the light source being disposed such that the laminated glass is irradiated from its periphery toward the inside with the light emitted from the light source.

A laminated vehicle windshield containing internal luminous information, includes a first glazing, a lamination interlayer, a second glazing and peripheral exterior and interior masking layers. The interior masking layer is discontinuous and includes one or more first discontinuities that form a first sign. The windshield also includes a first curved organic-light-emitting-diode device to illuminate the first sign.

The present specification relates to a novel compound, and a color conversion film, a backlight unit, and a display device, comprising the same.
