1. A light modulating device comprising:
a variable mirror comprising a plurality of lattice structures provided in a horizontal direction, the plurality of lattice structures comprising a material having a refractive index that changes based on a temperature of the material;
a distributed Bragg mirror spaced apart from the variable mirror and provided above the variable mirror in a vertical direction, the distributed Bragg mirror comprising a first material layer and a second material layer that are alternately stacked, and a refractive index of the first material layer being different from a refractive index of the second material layer;
a heating portion configured to apply heat the plurality of lattice structures and provided below the variable mirror in the vertical direction opposite to the distributed Bragg mirror; and
a substrate comprising a through hole and a metal plug provided in the through hole, the substrate being configured to support the heating portion.
