Abstract

The purpose of the present invention is to provide the following: an optical-device surface-sealing composition that makes it possible to fabricate an optical-device-using display with a low amount of warpage even if there is a large difference between the coefficients of linear expansion of substrates used in said display; a display with a low amount of warpage; and a manufacturing method therefor. The storage modulus of elasticity (G'(80)) of this optical-device surface-sealing composition, measured at 80° C. after said composition is heated from 40° C. to 80° C. at 5° C./min and then held at 80° C. for 30 minutes, is between 1.0×10and 2.0×10Pa.
