Abstract: A display apparatus includes a plurality of unit modules; and a cover configured to support the plurality of unit modules. Each of the plurality of unit modules includes: a substrate; a plurality of inorganic light emitting diodes provided on a mounting surface of the substrate; and an encapsulation layer formed on the mounting surface of the substrate to cover the plurality of inorganic light emitting diodes and the mounting surface of the substrate. The encapsulation layer includes a viscoelastic material having varying viscoelasticity based on temperature being applied to the viscoelastic material.
