Abstract
A light path control member according to one embodiment includes a first substrate; a first electrode disposed on the first substrate; a light conversion unit disposed on the first electrode; a second electrode disposed on the light conversion unit; and a second substrate disposed on the second electrode. The light conversion unit includes a light transmitting part, a high reflective part around the light transmitting part, and a transmittance variable part between the light transmitting part and the high reflective part. The light transmittance of the transmittance variable part is changed based on the voltage applied.
Claims8
