Abstract
Official abstract text for this publication.
Objects of the present invention are to provide a light-emitting element that does not readily deteriorate, a light-emitting device and an electronic device that do not readily deteriorate, and a method of fabricating the light-emitting element that does not readily deteriorate. A light-emitting element having an EL layer between a pair of electrodes is covered with a layer containing an inorganic compound and halogen atoms or a layer containing an organic compound, an inorganic compound, and halogen atoms, whereby deterioration by moisture penetration can be inhibited. Thus, a light-emitting element with a long life can be obtained.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of fabricating a light-emitting element, comprising the steps of: forming a first electrode; forming an EL layer over the first electrode; forming a second electrode over the EL layer; forming a layer containing an organic compound and an inorganic compound over the second electrode; and adding halogen atoms to the layer containing the organic compound and the inorganic compound by ion implantation, thereby forming a first sealing layer cont…
