Disclosed is a curable silicone composition. The composition comprises: (A) an organopolysiloxane having at least two alkenyl groups and at least one aryl group in each molecule; (B) a polyoxyalkylene compound represented by the general formula: XO&#x2014;(CHO)(CHO)(YO)&#x2014;X, wherein, each X represents a hydrogen atom, an alkyl group, an alkenyl group, an aryl group, an acryl group, or a methacryl group, provided that at least one X in each molecule is the alkenyl group, the acryl group, or the methacryl group, Y represents a divalent hydrocarbon group, n represents an integer of 3 to 6, p and q are integers satisfying: 2&#x2264;p&#x2264;100 and 0&#x2264;q&#x2264;50, and r represents 0 or 1; (C) an organopolysiloxane having at least two silicon bonded hydrogen atoms in each molecule; and (D) a catalyst for a hydrosilylation reaction. The composition forms a cured product having improved properties.

Curable silicone composition, cured product thereof, and optical display

A flexible laminate, in which it is possible to achieve both flexibility and durability, is disclosed. A flexible display using the flexible laminate is also disclosed. The flexible laminate includes one or more units of a laminate structure in which two hard layers interposing one or more intermediate layers therebetween are bonded together as one unit. The intermediate layer has viscoelasticity. When the flexible laminate is bent, a neutral plane is formed in each inner portion of the hard layers that are bonded together to interpose the intermediate layer therebetween.

Flexible laminate having viscoelasticity and flexible display using same

A flexible laminate for which increased flexibility and improved durability can coexist, and a flexible display provided with same, are disclosed. The flexible laminate has at least one unit of a laminated structure in which two hard layers closely adhere to each other with at least one intermediate layer therebetween. When the flexible laminate is bent, neutral planes are formed inside each of the hard layers that closely adhere to each other with the intermediate layer therebetween. The flexible laminate satisfies the following expression: a&#xd7;ln(tan &#x3b4;&#xd7;E/0.01)&#x2265;100. In the expression, a is any value ranging from 200 to 2,000, tan &#x3b4; represents a loss factor for a substance configuring the intermediate layer, and Erepresents an elastic modulus (MPa) of the substance configuring the intermediate layer.
