Claim 0:
1. An optical path control member comprising:
a first substrate;
a first electrode disposed on the first substrate;
a light conversion part disposed on the first electrode;
a second substrate disposed on the first substrate;
a second electrode disposed under the second substrate; and
an adhesive layer disposed between the light conversion part and the second electrode,
wherein the light conversion part includes a partition wall part and a reception part alternately disposed,
the reception part has a light transmittance that changes according to application of a voltage,
the adhesive layer includes a first interface between an upper surface of the adhesive layer and the second electrode and a second interface between a lower surface of the adhesive layer and the light conversion part,
the partition wall part includes
a first region from an upper surface of the partition wall part up to 30 μm toward the first substrate,
a third region from a lower surface of the partition wall part up to 30 μm toward the second substrate, and
a second region between the first region and the third region, and
a content of Si measured by X-ray photoelectron spectroscopy (XPS) in the first region is 2 at % or less.
