Abstract:
An optical property measurement apparatus includes: a main body which includes a plane-shape surface that is so disposed as to face the display portion; an optical sensor which receives light directed from an opening that is formed through the plane-shape surface; and a support portion which is disposed on a side of the plane-shape surface and keeps a constant distance between the display portion and the plane-shape surface; wherein a light shield portion that is so disposed as to enclose a circumferential area of the opening of the plane-shape surface and shields entrance of light from a region other than a measurement target region of the display portion when the optical property is measured.
