Abstract

A light-reflective anisotropic conductive adhesive used for anisotropic conductive connection of a light-emitting element to a wiring substrate includes a thermosetting resin composition, conductive particles, and light-reflective insulating particles. The light-reflective insulating particles are formed by subjecting titanium oxide particles to a surface treatment with one kind selected from the group consisting of AlO, SiO, SiO, ZnO, ZnO, and ZrO. The amount of the titanium oxide contained in the light-reflective insulating particles is 85 to 93%. The particle diameter of the light-reflective insulating particles is 0.2 to 0.3 μm, and the particle diameter of the conductive particles is 2 to 10 μm.
