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):

Photosensitive resin composition, wavelength conversion substrate and light emitting device

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

A phosphor substrate () includes a substrate (), phosphor layers (R,G, andB) which are disposed on the substrate () and which emit fluorescences (L) using incident excitation light (L), and a partition () surrounding side faces of the phosphor layers (R,G, andB), in which at least portions of the partition () in contact with the phosphor layers (R,G, andB) have light-scattering properties.

Phosphor substrate, display device, and electronic apparatus

A light-emitting device includes an excitation light source that emits excitation light; a first substrate which is disposed so as to face the excitation light source and on which a fluorescent layer and a first low-refractive-index layer are formed, the fluorescent layer being excited by the excitation light to emit fluorescence; and a barrier that surrounds side surfaces of the fluorescent layer, the side surfaces extending in a stacking direction of the excitation light source and the first substrate. At least a portion of the barrier that faces the fluorescent layer has a light-scattering property. The first low-refractive-index layer is located between the fluorescent layer and the first substrate. The first low-refractive-index layer has a refractive index lower than that of the first substrate.

Light-emitting device, and display apparatus, which can efficiently emit, to outside, fluorescence generated in fluorescent layer and can realize high-luminance light emission and in which generation of blurriness and fuzziness of display is suppressed
