Abstract: A CCM substrate (1) includes as a light-emitting layer on a substrate (11) a red conversion layer (142), a green conversion layer (152), and a light scattering layer (162); a bank (13) which stands on the substrate (11), and partitions the light-emitting layer; and a light-transmission suppressing layer (10) which is formed on at least a portion of a side surface (13a) of the bank (13) which is a surface facing the light-emitting layer, and suppresses light transmission between the light-emitting layers (the red conversion layer (142), the green conversion layer (152), and the light scattering layer (162)) with the bank (13) interposed therebetween by causing the light to be reflected or scattered, in which the light-transmission suppressing layer (10) is comprising metal or metal salt, and the bank (13) has a group, an ion, or a molecule for immobilizing the metal or metal ion.

Abstract: A phosphor layer composition, phosphor member, light source device, and projection device are provided that are capable of restraining reflection or scattering at interfaces between phosphor particles and a binder to improve the excitation-light absorption by, and the external quantum efficiency of, the phosphor particles. The present invention, in an aspect thereof, is directed to a phosphor layer composition including: phosphor particles 111 absorbing excitation light and emitting prescribed fluorescence; and a binder 112 composed of a translucent gel containing a metal alkoxide or a mixture of a metal alkoxide and a metal oxide, wherein the phosphor particles 111 are dispersed in the binder 112, and the phosphor particles 111 and the binder 112 differ in refractive index by 0.3 or less.

Abstract: A photosensitive resin composition includes a positive photosensitive resin having a photosensitive moiety that cleaves upon exposure to light, and a wavelength conversion material dispersed in the photosensitive resin. The photosensitive resin and the wavelength conversion material meet (i) to (iv): (i) The photosensitive moiety and the cleavage product of the photosensitive resin do not neutralize the wavelength conversion material; (ii) The photosensitive moiety and the cleavage product do not induce hydrolysis of the wavelength conversion material; (iii) The HOMOs of the photosensitive moiety and the cleavage product are lower than the LUMO of the wavelength conversion material; and (iv) The LUMOs of the photosensitive moiety and the cleavage product are higher than the HOMO of the wavelength conversion material. (Any combination of a chemically amplified photosensitive resin with an acidic photosensitive moiety or cleavage product and an acidic wavelength conversion material is excluded.)

Abstract: Provided is compatibility between adhesion to a substrate (lower layer) and durability improvement. An optical element includes a phosphor layer facing a lower layer, and a bonding layer keeping the phosphor layer in intimate contact with the lower layer. The phosphor layer includes an inorganic binder, and phosphor particle dispersed with the inorganic binder. The bonding layer includes an organic binder. The phosphor layer has a first surface facing the lower layer, a second surface opposite to the first surface, and a side surface connecting the first and second surfaces together. The bonding layer connects together the second surface, the side surface, and a surface of the lower layer to keep the phosphor layer in intimate contact with the lower layer.

Abstract: A cleaning solution is used, in a transparent antireflective structure that has, on one surface thereof, a plurality of convexities formed at a period equal to or shorter than wavelength in a visible light range, and that prevents, at the one surface, reflection of light entering the one surface, to clean a concavity defining a region between adjacent two of the plural convexities, the cleaning solution having a pH of 10.00 or more.
