Optical path control device and manufacturing method of the same

An optical path control device comprising:

• a first substrate having a first electrode disposed thereon;
• a second substrate disposed on the first substrate and having a second electrode disposed thereon;
• a light conversion layer disposed between the first substrate and the second substrate, and including a partition portion and a containing portion having suspended particles, wherein the partition portion and the containing portion are alternately disposed;
• an adhesive layer disposed between the first substrate and the light conversion layer;
• and
• a sealing portion disposed between the first substrate and the second substrate and surrounding the light conversion layer,
• wherein the sealing portion is disposed to fill a first injection hole disposed in the first substrate and the adhesive layer, and
• wherein the sealing portion comprises a protrusion that protrudes downward at the first injection hole and covers a lower surface of the first substrate around the first injection hole.
