LIGHT-REFLECTIVE CONDUCTIVE PARTICLE, ANISOTROPIC CONDUCTIVE ADHESIVE, AND LIGHT-EMITTING DEVICE

PROBLEM TO BE SOLVED: To provide a light-reflective conductive particle that does not degrade luminescent efficiency while not forming a light-reflecting layer causing increase of manufacturing cost in a light-emitting element, and does not generate difference between light emission color and reflected light color of the light-emitting element, when manufacturing a light-emitting device by subjecting a light-emitting element such as a light-emitting diode to flip-chip mounting on a wiring board by using an anisotropic conductive adhesive. SOLUTION: The light-reflective conductive particle for this anisotropic conductive adhesive used for subjecting a light-emitting element to anisotropic conductive connection to a wiring board is formed with: a core particle coated with a metal material; and a light-reflective layer located on a surface thereof and formed of light-reflective inorganic particles each having a refractive index of ≥1.52. For the light-reflective inorganic particle having a refractive index of ≥1.52, a titanium oxide particle, a zinc oxide particle or an aluminum oxide particle may be used. COPYRIGHT: (C)2011,JPO&INPIT
