Abstract

To provide an ultraviolet curable type liquid silicone composition which is curable at 100°C or lower, and can suppress curing inhibition caused by an image display device member.SOLUTION: An ultraviolet curable type liquid silicone composition contains (A-1) organopolysiloxane having at least two alkenyl groups, (A-2) one or more selected from straight-chain organopolysiloxane having one aliphatic unsaturated group at only one terminal of a molecular chain and a silane compound having one aliphatic unsaturated bond group in one molecule, (B-1) organohydrogenpolysiloxane of general formula (1) (in the general formula (1), R1 and R2 are hydrocarbon groups, a and b are integers in which a / (a+b) is 0.2 or more and a+b is 15 or more), and (C) a photoactive hydrosilylation reaction catalyst, where a ratio of the number of moles of the Si-H groups to the number of moles of the aliphatic unsaturated bonds is 0.9 to 1.5, and a ratio of the Si-H groups derived from the component (B-1) to the total number of the Si-H groups is 30 mol% or more.SELECTED DRAWING: None
