The purpose of the present invention is to provide: a sealant that has a viscosity which is suitable for application in an inkjet method, and a cured product of which has a low dielectric constant; and a method of manufacturing a display device using the sealant. For this purpose, the sealant comprises (A) a cycloaliphatic epoxy compound and (B) an oxetane compound. The sealant has a viscosity measured by an E-type viscometer under the conditions of 25 DEG C and 20 rpm of 10 to 30 mPa.s, and a cured product thereof cured under UV-LEDs having a wavelength of 395 nm, at an illuminance of 1000 mW/cm2 and a cumulative amount of light of 1500 mJ/cm2 has a dielectric constant at a frequency of 100 kHz of 3.0 or less.
