Abstract
An organic light-emitting display device includes a color filter disposed on a light-emitting structure. An over-coat layer may be disposed between the color filter and the light-emitting structure. Diffusion-beads are dispersed in the over-coat layer. Thus, in the organic light-emitting display device according to the aspect of the present disclosure, light efficiency may be increased without a process of forming micro-lens.
