Provided is a display apparatus including a substrate, a plurality of light emitting device (LED) elements arranged in front of the substrate, a transmission layer formed on a front surface of the substrate to entirely cover the plurality of LED elements, a first polarization member arranged in front of the transmission layer, and a second polarization member arranged on a front surface of the first polarization member and allowing external light to be incident thereon, wherein the transmission layer is provided such that polarization of external light polarized through the second polarization member and the first polarization member is maintained in a course of the polarized external light passing through the transmission layer, being reflected by the front surface of the substrate or the plurality of LED elements and being directed to the first polarization member.

Light emitting diode display apparatus

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.
