Abstract: The present disclosure relates to an organic light-emitting diode display device that comprises a first substrate on which first, second and third subpixels each including an emission area and a non-emission area are defined; first, second and third light-emitting diodes disposed in the first, second and third subpixels on the first substrate, respectively; a second substrate over the first, second and third light-emitting diodes; and a scattering pattern corresponding to the first subpixel and disposed over the first light-emitting diode or under the first substrate, wherein the first subpixel has an area reflectance higher than the second and third subpixels.
