1. An organic light-emitting device comprising:
a first panel; a second panel disposed to face the first panel with a gap between the first panel and the second panel; and a coating layer inserted between the first panel and the second panel so as to contact the first panel and the second panel, wherein the first panel comprises a first substrate and a luminous part formed on one of main surfaces of the first substrate, the luminous part comprising an organic layer in structure and emitting light opposite to the first substrate, the second panel comprises a second substrate and a circular polarizing film disposed in a region through which the light emitted from the luminous part of the first panel passes, the coating layer comprises a resin part that transmits the light emitted from the luminous part and a plurality of particles dispersed in at least some region of the resin part, each of the plurality of particles is formed of a material selected from the group consisting of synthetic zeolite, aluminum oxide, calcium chloride, calcium oxide, active anhydrous calcium sulfate, magnesium oxide, magnesium perchlorate, magnesium sulfate, phosphorus oxide, potassium carbonate, potassium hydroxide, silica gel, sodium hydroxide, sodium sulfate, and zinc chloride, when a particle size parameter is plotted on a horizontal axis and scattering efficiency is plotted on a vertical axis, an average particle size D50 of the plurality of particles is set in a range equal to or greater than a value of the particle size parameter at which the scattering efficiency becomes maximum, a layer thickness of the coating layer is not less than 10 μm and not more than 20 μm, and the plurality of particles in the resin part are dispersed at a density at which the particles do not overlap one another when the second panel is viewed in plan view. |
