Abstract
A light path control member according to an embodiment comprises: a first substrate including an effective area and an ineffective area; a first electrode disposed on the first substrate; a second substrate disposed on the first substrate and including an effective area and an ineffective area; a second electrode disposed under the second substrate; and a light conversion unit disposed between the first electrode and the second electrode. The light conversion unit includes an alternating arrangement of partition wall parts and reception parts. A first hole passing through the first substrate is formed in at least one of the effective area or the ineffective area of the first substrate. A second hole passing through the first substrate is formed in at least one of the effective area or the ineffective area of the second substrate. A first connection electrode is disposed in the first hole, and a second connection electrode is disposed in the second hole.
