Abstract
Official abstract text for this publication.
A light-reflective conductive particle for an anisotropic conductive adhesive used for anisotropic conductive connection of a light-emitting element to a wiring board includes a core particle coated with a metal material and a light-reflecting layer formed from light-reflective inorganic particles having a refractive index of 1.52 or more on a surface of the core particle. Examples of the light-reflective inorganic particles having a refractive index of 1.52 or more include titanium oxide particles, zinc oxide particles, or aluminum oxide particles.
First claim
Opening claim text (preview).
The invention claimed is: 1. A light-reflective conductive particle for an anisotropic conductive adhesive used for anisotropic conductive connection of a light-emitting element to a wiring board, comprising a core particle coated with a metal material and a light-reflecting layer formed from light-reflective inorganic particles having a refractive index of 1.52 or more on a surface of the core particle, wherein the light-reflecting layer contains a thermoplastic resin. 2. The light-reflective conductive particle according to claim 1 , wherein the metal material with which the core particle is coated is gold, nickel, or copper. 3. The light-reflective conductive particle according to claim 1 , wherein the core particle itself is a gold, nickel, or copper particle. 4. The light-reflective conductive particle according to claim 1 , wherein the core particle is formed by coating gold, nickel or copper on a resin particle. 5. The light-reflective conductive particle according to claim 1 , wherein the core particle has a particle size of 1 to 20 μm, and the light-reflecting layer has a layer thickness of 0.5 to 50% of the particle size of the core particle. 6. The light-reflective conductive particle according to claim 1 , wherein the light-reflective inorganic particle is at least one type of inorganic particles selected from titanium oxide particles, zinc oxide particles, and aluminum oxide particles.
