Abstract

A highly reliable light-emitting device and a manufacturing method thereof are provided. A light-emitting element and a terminal electrode are formed over an element formation substrate; a first substrate having an opening is formed over the light-emitting element and the terminal electrode with a bonding layer provided therebetween; an embedded layer is formed in the opening; a transfer substrate is formed over the first substrate and the embedded layer; the element formation substrate is separated; a second substrate is formed under the light-emitting element and the terminal electrode; and the transfer substrate and the embedded layer are removed. In addition, an anisotropic conductive connection layer is formed in the opening, and an electrode is formed over the anisotropic conductive connection layer. The terminal electrode and the electrode are electrically connected to each other through the anisotropic conductive connection layer.
