Light route control member and display device comprising same

A display device comprising:

• a display panel;
• and
• a light route control member disposed on the display panel,
• wherein the light route control member includes:
• 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 part disposed between the first electrode and the second electrode,
• wherein the light conversion part includes a partition wall part and a receiving part that are alternately arranged,
• wherein light emitted from the light source in a direction of the first substrate and the second substrate is transmitted,
• wherein the light moves from the first substrate to the second substrate,
• wherein a light transmittance is changed according to an application of voltage to the receiving part,
• wherein the receiving part includes a dispersion and light conversion particles dispersed in the dispersion,
• wherein a contact surface of the partition wall part and the receiving part has an inclination angle with respect to a reference axis in a direction perpendicular to the upper surface of the first substrate,
• wherein the inclination angle is 1° to 10°,
• wherein the contact surface is inclined to increase a width of the partition wall part while extending in a moving direction of the light,
• wherein the contact surface is inclined to decrease a width of the receiving part while extending in the moving direction of the light, and
• wherein the partition wall part includes 0.01 wt % to 10 wt % of an antistatic agent.
