Abstract: The purpose of the present invention is to provide graphene in a form that renders the graphene highly dispersible and enables the graphene to retain high electroconductivity and ionic conductivity when used as a raw material for producing electrode materials. The present invention is a graphene dispersion which includes graphene dispersed in a solvent including 50 mass% or more N-methylpyrrolidone. When this graphene dispersion is diluted with N-methylpyrrolidone to a graphene content by weight of 0.000013, the dilution has a weight absorptivity coefficient, as measured at a wavelength of 270 nm and calculated using the following equation (1), of 25,000-200,000 cm-1. Weight absorptivity coefficient (cm-1) = absorbance/{0.000013×(optical path length (cm) of cell)} (1)

Abstract: PROBLEM TO BE SOLVED: To increase the electric resistance while maintaining the high light- shielding properties of a light-shielding thin film containing a resin and specified particles coated with an insulating film by forming the light-shielding thin film so as to have specified or higher optical density and specified or higher electric resistance. SOLUTION: The light-shielding thin film contains a resin and titanium black TiNxOy (0 =2.5 optical density(OD) and >=1011 Ω.cm electric resistance. As for the method for producing the titanium black particles, for example, a method to heart a mixture of titanium dioxide and metal titanium in a reducing atmosphere to reduce the mixture can be used. As for the method for forming the insulating film on the surface of titanium black particles, for example, a method to treat the titanium black in an ethylalcohol solution of silicon teraethoxide can be used.

Abstract: PROBLEM TO BE SOLVED: To provide a color filter by which uniform cell gap can be realized and which has satisfactory productivity. SOLUTION: After a color layer and a transparent conductive film are formed, a resin light shielding layer is provided to form a black matrix and a spacer in which a photoresist layer for patterning the resin light shielding layer remains as an uppermost layer is formed. Thus, the color filter with the fixed spacer excellent in productivity can be realized in the same number of photolithographic stages as the usual color filter wherein no fixed spacer is used.
