Optical path control member and display device comprising same

An optical path control member comprising:

• a first substrate;
• a first electrode disposed on the first substrate;
• a second substrate disposed on the first substrate;
• a second electrode disposed under the second substrate;
• and
• a light conversion unit disposed between the first electrode and the second electrode,
• wherein the light conversion unit includes a barrier rib part, an accommodating part, and a base part,
• wherein a light conversion material including a dispersion liquid, light conversion particles, and a dispersant is disposed in the accommodating part,
• wherein the dispersant includes a first dispersant, a second dispersant, a third dispersant, and a fourth dispersant,
• wherein the first dispersant and the second dispersant are non-polar dispersants,
• wherein the third dispersant and the fourth dispersant are polar dispersants,
• wherein the second dispersant is formed by aggregating the first dispersants,
• wherein the third dispersant is formed by the first dispersant losing electrons,
• wherein the fourth dispersant is formed by bonding the second dispersant and the third dispersant.
