Abstract: An organic light-emitting display device includes a thin film encapsulation layer, a transmission pattern, and a color-adjusting pattern. The thin film encapsulation layer covers an organic light-emitting diode. The transmission pattern is in a light-emitting area on the thin film encapsulation layer. The color-adjusting pattern includes ceramic particles as a coloring agent and is in a non-light-emitting area surrounding the light-emitting area on the thin film encapsulation layer.
