Abstract: An object is to improve productivity related to a laser light irradiation step in a bonding technique of substrates using glass frit. A highly airtight sealing structure or a highly airtight light-emitting device, which can be manufactured with high productivity, is provided. When a glass layer by melting glass frit or a sintered body by sintering glass frit is irradiated with laser light, in order to increase the efficiency, a light-absorbing material is attached to a surface of the glass layer. The laser light irradiation is performed on the light-absorbing material and the glass layer. The substrates are fixed with the glass layer therebetween.

Abstract: A display device with low power consumption and high display quality is provided. The display device includes first and second electrodes. One pixel includes a region in which the distance between the first electrode and the second electrode is constant and a region in which the distance varies; this structure allows the switching operation of liquid crystal to start in a predetermined region, thereby improving the stability of the operation of the liquid crystal. A pixel region is divided into two regions in which the liquid crystals are aligned in the two respective directions when switching is performed, whereby viewing angle characteristics are improved. Furthermore, the supply of a potential to a third electrode suppresses alignment disorder of the liquid crystal and improves the display quality.

Abstract: In a light-emitting device where reflective electrodes are regularly arranged, occurrence of interference fringes due to reflection of light reflected by the reflective electrode is inhibited. A surface of the reflective electrode of a light-emitting element is provided with a plurality of depressions. The shapes of the plurality of depressions are different from each other and do not have rotational symmetry. Irregularity of the surface shape of the reflective electrode is increased, which inhibits interference of light reflected by the reflective electrode. To form the plurality of depressions in the surface of the reflective electrode, for example, a surface of an insulating layer that is a base of the reflective electrode is made uneven. Reflecting the surface shape of the insulating layer, the reflective electrode has an uneven surface.
