This invention provides a curable composition for use, for example, in liquid crystal displays, that can form a cured product which can be largely deformed upon exposure to external pressure (that is, uneven applied force in the preparation of a substrate can be absorbed) and causes no significant lowering in recovery even under high pressure (that is, the dependency of recovery upon pressure is small). The curable composition can form a cured product satisfying the following index formula in a load-unload test with a microhardness tester: |H1-H2|/|P1-P2| >= 0.35 and |R1-R2|/|P1-P2| <= 15 wherein H1 and H2 represent total degree of deformation of spacers respectively having upper sectional areas of 40 ± 5 mum^2 and 150 ± 5 mum^2, mum; P1 and P2 represent pressures applied to the spacers respectively having upper sectional areas of 40 ± 5 mum^2 and 150 ± 5 mum^2, mN/mum^2; and R1 and R2 represent elastic recovery of the spacers respectively having upper sectional areas of 40 ± 5 mum^2 and 150 ± 5 mum^2, %. |
