Organic light emitting display apparatus
First Claim
1. An organic light emitting display apparatus comprising:
- a substrate;
a plurality of organic light emitting elements on the substrate;
an encapsulation substrate covering the organic light emitting elements; and
a scattering layer comprising;
a resin; and
a plurality of scattering particles distributed in the resin, and comprising a variety of particle sizes in a first range from about 500 nm to about 800 nm,wherein ones of the scattering particles having a first particle size comprise a highest concentration of the scattering particles, andwherein a concentration of other ones of the scattering particles is inversely proportional to a magnitude of a difference in particle size between the other ones of the scattering particles and the ones of the scattering particles having the first particle size.
