Abstract
An optical path control member according to an embodiment comprises: a first substrate; a first electrode disposed on the upper part of the first substrate; a second substrate disposed on the first substrate; a second electrode disposed on the lower part of the second substrate; and an optical conversion unit disposed between the first electrode and the second electrode. The optical conversion unit includes partition wall portions and receiving portions that are alternately disposed. The receiving portions change optical transmittance in response to the application of voltage, and include a dispersion and optical conversion particles dispersed in the dispersion. The refractive index ratio of the partition wall portions and the receiving portions is 1:0.95 to 1:1.05.
