Light-Emitting Device, Module, Electronic Device, and Method for Manufacturing Light-Emitting Device

Abstract

A light-emitting element, a bonding layer, and a frame-like partition are formed over a substrate. The partition is provided to surround the bonding layer and the light-emitting element, with a gap left between the partition and the bonding layer. A pair of substrates overlap with each other under a reduced-pressure atmosphere and then exposed to an air atmosphere or a pressurized atmosphere, whereby the reduced-pressure state of a space surrounded by the pair of substrates and the partition is maintained and atmospheric pressure is applied to the pair of substrates. Alternatively, a light-emitting element and a bonding layer are formed over a substrate. A pair of substrates overlap with each other, and then, pressure is applied to the bonding layer with the use of a member having a projection before or at the same time as curing of the bonding layer.
