Abstract: An optical path control member according to an embodiment comprises: a first substrate; a first electrode disposed on the first substrate; an optical conversion part disposed on the first electrode; a second substrate disposed on the first substrate; a second electrode disposed below the second substrate; and an adhesive layer disposed between the optical conversion part and second electrode. The optical conversion part comprises partition parts and accommodation parts which are alternately disposed. The accommodation parts comprise a dispersion liquid and optical conversion particles. The light transmittance of the accommodation parts changes in accordance with the application of voltage, and the driving speed measured by 85% reach time is less than 6 seconds.
