Beschreibung
Zusammenfassung:	An optical path control device according to an embodiment includes: a substrate; a first phase retardation layer on the substrate; a second phase retardation layer on the first phase retardation layer; a viewing angle control layer on the second phase retardation layer; and a polarizing layer on the viewing angle control layer, wherein the second phase retardation layer is in direct contact with the viewing angle control layer. 根据实施例的光路控制装置包括：基板；基板上的第一相位延迟层；第一相位延迟层上的第二相位延迟层；第二相位延迟层上的视角控制层；以及视角控制层上的偏振层，其中第二相位延迟层与视角控制层直接接触。
