Patent ID: 8207669

Claim:
An organic light emitting display device comprising: a first substrate; a plurality of organic light emitting devices on the first substrate, the organic light emitting devices comprising: a plurality of first electrodes on the first substrate; a plurality of organic light emitting layers on the first electrodes; and at least one second electrode on the organic light emitting layers; a second substrate arranged opposite and substantially parallel to the first substrate with the organic light emitting devices therebetween; a plurality of spacers between the organic light emitting devices and the second substrate; and a plurality of fillers alternately arranged with the spacers and configured to fill in space between the first substrate and the second substrate, wherein at least portions of the spacers overlap with a plurality of light emitting regions defined by the organic light emitting layers and the first electrodes, wherein the spacers and fillers contact the at least one second electrode, and wherein the spacers and the fillers have a transmittance between about 70% to 100%, and a difference in a refractive index between the spacers and the fillers is between about 0.01 to 0.4.
