More Information
Summary:The present disclosure provides a light emitting diode (LED) package, which ensures the reliability during use while adopting an LED chip of higher output. The LED package includes an LED chip, which has a front and a back facing opposite sides in the thickness direction z, and a first back electrode provided at the back surface; a first terminal in conduction with the first back electrode; and a first bonding layer, configured to bond the first back electrode and the first terminal 201; wherein the composition of the first bonding layer includes a metal eutectic composition containing Au, and when the LED chip is viewed in the thickness direction z, a first bent portion which is recessed toward the inner side of the periphery of the first back electrode is formed in the first bonding layer.
