Abstract: The object can be achieved by the following structure. A material whose value of fracture toughness is greater than or equal to 1.5 [MPa·m1/2] is used for a base substrate and a counter substrate which hold a liquid crystal material therebetween; a first sealant containing liquid crystal contaminants at less than or equal to 1×10−4 wt % is provided so as be in contact with the liquid crystal material and to surround the liquid crystal material seamlessly; the second sealant is provided to surround the first sealant; and the base substrate and the counter substrate which hold the liquid crystal material therebetween using the first sealant and the second sealant are bonded with a bond strength of greater than or equal to 1 [N/mm2].

Abstract: A flicker of an FFS liquid crystal display device that is driven at a low refresh rate is reduced. In an FFS liquid crystal display, a pixel electrode and a first common electrode included in a liquid crystal element are formed on an element substrate side, and a second common electrode is formed on another substrate (counter substrate) side. By making the first and second common electrodes have the same potential, generation of a residual DC voltage can be suppressed in a pixel. Thus, even when a refresh rate is lowered, change in transmittance of a pixel can be suppressed in a data retention period, so that a flicker can be reduced.

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.
