An organic light-emitting device with a plurality of subpixels, each subpixel including an emission region and a non-emission region, the organic light-emitting device including a substrate; an anode on the substrate, the anode including patterns that separately correspond to respective ones of the plurality of subpixels; an organic layer on the anode, the organic layer being common to the plurality of subpixels; and a cathode on the organic layer, the cathode including a plurality of subcathodes that each correspond to at least one of the subpixels and that allow light to pass through in emission regions, wherein adjacent two of the subcathodes overlap with each other in non-emission regions.
