There is one in which a plurality of substrates are bonded together via a sealing material with a spacer covered with an adhesive layer interposed therebetween, and a liquid crystal is sealed between both substrates inside the sealing material. In this case, the spacer is made of particles of glass, resin, or the like having a constant size, and is for maintaining the interval between both substrates with high precision and uniforming the display quality of the liquid crystal. The adhesive layer is for fixing the spacers to the facing surfaces of the alignment films of both substrates so that the spacers do not move even if an external force is applied.

系溶媒を使用するようになってきている。By the way, in order to interpose the spacer between both the substrates, a method is generally adopted in which the spacer is dispersed and dispersed on the upper surface of the alignment film of one substrate. There are two methods for spraying spacers: a dry spraying method in which only the spacers are directly sprayed from the nozzle, and a wet spraying method in which the spacers are sprayed together with the solvent from the nozzles. Generally, the wet spraying method with good dispersion uniformity is adopted. Has been done. In the conventional wet spray method, chlorofluorocarbon is used as a solvent, and the spacer is sprayed together with the chlorofluorocarbon from the nozzle, but the chlorofluorocarbon is evaporated before reaching the upper surface of the alignment film of one of the substrates, so that only the spacer of one of the substrates is evaporated. It was scattered on the upper surface of the alignment film.
However, due to recent freon regulations, alcoholic solvents such as isopropyl alcohol and ethyl alcohol have been used in place of this.

の製造方法を提供することにある。However, when the solvent for the wet spraying method was changed from CFC to an alcohol solvent, it was found that the following problems, which were not a problem with CFC, occurred. One is that when the thickness of the adhesive layer of the spacer is thicker than 0.1 μm, the adhesive layer easily absorbs the alcohol solvent and swells. When contained, and in contact with the alignment film in this state, the alcohol-based solvent contained in the adhesive layer acts on the alignment film, and the alignment regulating force of the alignment film decreases.
It has been found that the display quality may be impaired.
The other is that the thickness of the adhesive layer of the spacer is 0.05 μm.
If the thickness is made thinner, the amount of alcohol solvent contained in the adhesive layer will be small and the alignment regulating force of the alignment film will not be reduced, but the adhesive force of the spacer, which is the original purpose of the adhesive layer, will be reduced. However, it has been found that the spacer may move to cause a gap defect, and display quality may be impaired. An object of the present invention is to provide a liquid crystal display device which can prevent the alignment regulating force of the alignment film from decreasing and the fixing force of the spacers to decrease, and a manufacturing method thereof.
