A pyrromethene-boron complex that can be used as a red light fluorescent material with improved emission efficiency and color purity is provided. A pyrromethene-boron complex represented by the following general formula (1) and satisfying at least one of (A) and (B) is provided:

Pyrromethene boron complex, light emitting element using same, display device, lighting device, color conversion composition, color conversion film, color conversion substrate, light source unit and display

A light-emitting device is described that includes a plurality of partially drivable light sources, and a color conversion component configured to convert at least part of incident light from at least part of the light sources and emit outgoing light falling in a different wavelength region from the incident light, where the color conversion component includes a pyrromethene derivative.

Light-emitting device, display and color conversion substrate

An organic luminescent material suitable for color conversion material used for a liquid crystal display or LED lighting, excellent in luminous efficiency and durability, to which a pyrromethene-boron complex or a color conversion composition containing the pyrromethene-boron complex contributes, is provided.

Pyrromethene-boron complex, color-changing composition, color-changing film, light source unit including same, display, and lighting

A pyrromethene-boron complex is a compound represented by general formula (1). In general formula (1), X is C&#x2014;Ror N. Rto Rare each a group selected from prescribed groups, where Rand Rare selected from among the groups other than a substituted or unsubstituted aryl group and a substituted or unsubstituted heteroaryl group. Rand Rare groups not containing a heteroaryl group with at least two condensed rings. At least one of Rto Ris a group containing a fluorine atom.
