摘要： A method for exposing an electrode terminal covered with an organic film in a light-emitting device without damaging the electrode terminal is provided. In a region of the electrode terminal to which electric power from an external power supply or an external signal is input, an island-shaped organic compound-containing layer is formed and the organic film is formed thereover. The organic film is removed by utilizing low adhesion of an interface between the organic compound-containing layer and the electrode terminal, whereby the electrode terminal can be exposed without damage to the electrode terminal.

摘要： It is an object to provide a flexible light-emitting device with high reliability in a simple way. Further, it is an object to provide an electronic device or a lighting device each mounted with the light-emitting device. A light-emitting device with high reliability can be obtained with the use of a light-emitting device having the following structure: an element portion including a light-emitting element is interposed between a substrate having flexibility and a light-transmitting property with respect to visible light and a metal substrate; and insulating layers provided over and under the element portion are in contact with each other in the outer periphery of the element portion to seal the element portion. Further, by mounting an electronic device or a lighting device with a light-emitting device having such a structure, an electronic device or a lighting device with high reliability can be obtained.

摘要： When a hollow structure in which a light-emitting element is provided between a pair of substrates is used in order to prevent oxygen or moisture from reaching the light-emitting element, light leakage to an adjacent pixel easily occurs as compared to a structure in which a space between a pair of substrates is filled with a resin such as an adhesive. In order to reduce light leakage to an adjacent pixel in the hollow structure, a light-blocking spacer is formed over a partition to keep the distance between the pair of substrates uniform. The cross-sectional shape of the light-blocking spacer is a trapezoid having a lower side shorter than an upper side.

摘要： A light-emitting device and a lighting device each of which includes a plurality of light-emitting elements exhibiting light with different wavelengths are provided. The light-emitting device and the lighting device each have an element structure in which each of the light-emitting elements emits only light with a desired wavelength, and thus the light-emitting elements have favorable color purity. In the light-emitting element emitting light (λR) with the longest wavelength of the light with different wavelengths, the optical path length from a reflective electrode to a light-emitting layer (a light-emitting region) included in an EL layer is set to λR/4 and the optical path length from the reflective electrode to a semi-transmissive and semi-reflective electrode is set to λR/2.
