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,whereinthe first panel comprises a first substrate and a luminous part formed on one main surface of the first substrate, the luminous part comprising an organic layer in structure and emitting light opposite to the first substrate,the coating layer transmits the light from the luminous part,a plurality of first particles are dispersed in at least some region of the coating layer,each of the plurality of the first particles is formed of a material selected from the group consisting of synthetic zeolite, aluminum oxide, calcium oxide, calcium chloride, 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,the plurality of the first particles constitute a first particle group,a plurality of second particles that constitute a second particle group are also dispersed in at least some region of the coating layer, the plurality of second particles that constitute the second particle group being different from those that constitute the first particle group,the second particles that constitute the second particle group include any of polyethylene, polypropylene, polymethylpentene, polyvinyl chloride, polytetrafluoroethylene, polystyrene, polymethyl methacrylate, polyethylene terephthalate, polybutylene terephthalate, polyamide, polyimide, polysulfone, polyphenylene oxide, polyacetal, an epoxy resin, a phenol resin, a melamine resin, and an unsaturated polyester resin, or a resin that has a bridged structure and is selected from the group consisting of divinylbenzene polymer, divinylbenzene-styrene copolymer, divinylbenzene-acrylic ester copolymer, diallyl phthalate polymer, and triallyl isocyanurate polymer, anda relationship of D50(2)>
D50(1) is satisfied,whereD50(1) is defined as an average particle size of the plurality of first particles that constitute the first particle group, andD50(2) is defined as an average particle size of the plurality of second particles that constitute the second particle group.

Abstract
A display panel includes a EL panel part, a CF panel part, and a resin layer. Light is extracted from a luminous part including an organic luminous layer in the EL panel part in a direction of an arrow. The resin layer is formed to cover an upper surface of the EL panel part. Transmittance of the light from the EL panel part is 80% or higher. The resin layer includes a resin part and a plurality of particles dispersed in the resin part. The particles are formed of synthetic zeolite having a refractive-index ratio to the resin part of 1.0 or more and a particle size of 2 μm or more.
