Abstract: An optical path control device can include a first substrate having a first electrode disposed thereon, a second substrate disposed on the first substrate and having a second electrode disposed thereon, and a light conversion layer disposed between the first substrate and the second substrate and including a partition portion and a containing portion including suspended particles, where the partition portion and the containing portion are alternately disposed. The optical path control device can further include an adhesive layer disposed between the first substrate and the light conversion layer, a sealing portion disposed between the first substrate and the second substrate and surrounding the light conversion layer, and a dam portion disposed between the first substrate and the second substrate and disposed on an outside of the sealing portion.

Abstract: An optical path control device and a display device including the same are discussed. The optical path control device can include a first substrate, a first electrode disposed on the first substrate, a second electrode disposed on the first substrate, a second electrode disposed under the second substrate, and a photoconversion layer disposed between the first electrode and the second electrode. The photoconversion layer can include a partition portion and a receiving portion that are alternately arranged, and the receiving portion can include suspended particles. The first electrode can include a first auxiliary electrode disposed on a first area of the first substrate and a second auxiliary electrode disposed on a second area of the first substrate.
