A method of manufacturing a semi-finished blank for a varifocal liquid crystal lens constituted such that a liquid crystal holder is formed between the front of a first substrate and the rear of a second substrate that is opposite the first substrate, the method comprising: a liquid crystal coating step of coating a liquid crystal holder with a liquid crystal material by inkjet, the liquid crystal holder being formed in a region on the front of a first substrate, an adhesive agent coating step of coating the front of the first substrate and/or the rear of a second substrate with an adhesive agent, such that the adhesive agent surrounds the liquid crystal holder while leaving a space from the liquid crystal holder; a pressure reduction step of reducing the pressure inside a sealed vessel that holds the first substrate and the second substrate, with respect to atmospheric pressure; an affixing step of affixing the second substrate to the front of the first substrate in the reduced pressure environment produced in the pressure reduction step; a standby step of continuing the affixed state between the first substrate and the second substrate for a specific length of time in the reduced pressure environment produced in the pressure reduction step after the substrates have been affixed; and a pressure restoration step of restoring the pressure of the sealed vessel to atmospheric pressure after the standby step; wherein the liquid crystal material is coated in step S4 up to an amount at which the liquid crystal material is held on the liquid crystal holder by surface tension after the sealed vessel has been restored to atmospheric pressure, and, in the standby step, the space is transformed into a sealed space by the adhesive agent forming a ring-shaped region around the outer periphery of the sealed space. a liquid crystal coating step of coating a liquid crystal holder with a liquid crystal material by inkjet, the liquid crystal holder being formed in a region on the front of a first substrate, an adhesive agent coating step of coating the front of the first substrate and/or the rear of a second substrate with an adhesive agent, such that the adhesive agent surrounds the liquid crystal holder while leaving a space from the liquid crystal holder; a pressure reduction step of reducing the pressure inside a sealed vessel that holds the first substrate and the second substrate, with respect to atmospheric pressure; an affixing step of affixing the second substrate to the front of the first substrate in the reduced pressure environment produced in the pressure reduction step; a standby step of continuing the affixed state between the first substrate and the second substrate for a specific length of time in the reduced pressure environment produced in the pressure reduction step after the substrates have been affixed; and a pressure restoration step of restoring the pressure of the sealed vessel to atmospheric pressure after the standby step; wherein the liquid crystal material is coated in step S4 up to an amount at which the liquid crystal material is held on the liquid crystal holder by surface tension after the sealed vessel has been restored to atmospheric pressure, and, in the standby step, the space is transformed into a sealed space by the adhesive agent forming a ring-shaped region around the outer periphery of the sealed space.
