摘要： A QD particle dispersion contains a surface modification compound that protects a surface of QD phosphor particles dispersed in a solvent. The surface modification compound includes a heteroatom-containing functional group and a chain-type saturated hydrocarbon group. The QD particle dispersion is configured such that the absolute value of a difference between the surface free energy of an underlayer that provides a foundation for forming a QD layer in the light-emitting element and the surface free energy of the QD layer is 5 mN/m or less.

摘要： An object of the present invention is to enhance a display quality of a liquid crystal display panel by causing a contour of a display region not to be noticeable. A display region of a liquid crystal display panel (100) includes a normal display region (101a) and a boundary display region (101c), an image being displayed more darkly in the boundary display region (101c), which is in contact with a black light blocking part (101b), than in the normal display region (101a).
