Claim Text:
1. An image display sealant dam composition that comprises: (A) a polyorganosiloxane having a mercaptoalkyl group bonded to a silicon atom, the polyorganosiloxane (A) having a viscosity at 23° C. of 20 to 25000 cP; (B) an aliphatic unsaturated group-containing polyorganosilane including an aliphatic unsaturated group-containing a linear polyorganosiloxane (B1) represented by the following formula (I): wherein in the formula (I): each R each R group independently represents a C1 to C6 alkyl group or a C6 to C12 aryl group, and 1 to 60 mol % of the total R groups are C6 to C12 aryl groups, and the letter n is a value such that the viscosity at 23° C. is 10,000 to 1,000,000 cP, and a branched polyorganosiloxane (B2) having SiO (C) a photoreaction initiator; (D) at least one silane compound; and (E) an MQ resin having a weight average molecular weight of 2,000 to 2,500,000 and/or an MDQ resin having a weight average molecular weight of 2,000 to 1,000,000; wherein a ratio of the number of the mercaptoalkyl groups in (A) to the number of the aliphatic unsaturated groups in (B) is 0.5 to 3.0; (E) is in an amount of 30 to 200 parts by weight per 100 parts by weight of (B); and said dam composition has a viscosity at 23° C. of 20,000 to 150,000 cP, wherein a thixotropic ratio V
