Abstract

A light-emitting device in which reduction in performance due to moisture is suppressed is provided. The light-emitting device has a structure in which a partition having a porous structure surrounds each of light-emitting elements. The partition having a porous structure physically adsorbs moisture; therefore, in the light-emitting device, the partition functions as a hygroscopic film at a portion extremely close to the light-emitting element, so that moisture or water vapor remaining in the light-emitting device or entering from the outside can be effectively adsorbed. Thus, reduction in performance of the light-emitting device due to moisture or water vapor can be effectively suppressed.
