A display member comprising: a light transmission layer which has a principal surface on which a plurality of pixels are two-dimensionally arranged; and a metal layer which partially covers the principal surface, each of the plurality of pixels including one or more selected from the group consisting of: a first region which has a plurality of first grooves or ridges each of which extends in a longitudinal direction in a first angle range of -10° to +10° with respect to a first direction which is parallel to the principal surface; a second region which has a plurality of second grooves or ridges each of which extends in a longitudinal direction in a second angle range of -65° to +65° with respect to a second direction which is parallel to the principal surface and is perpendicular to the first direction, the plurality of second grooves or ridges forming a diffraction structure on an interface between the light transmission layer and the metal layer or on a surface of the metal layer; a third region which is flat; and a fourth region which has a plurality of third grooves or ridges each of which extends in a longitudinal direction in the second angle range, the plurality of third grooves or ridges forming an anisotropic light-scattering structure on the interface between the light transmission layer and the metal layer or on the surface of the metal layer, one or more of the plurality of pixels including the first region, one or more of the plurality of pixels including the second region, the metal layer not covering at least part of the first region and covering the second region, and also covering the third region and the fourth region when the third region and the fourth region are present, the display member being configured to display a first image corresponding to a distribution of the first region when the display member is illuminated with white light and transmitted light is observed and display a second image when the display member is illuminated with white light and diffracted light which exits the diffraction structure is observed. a light transmission layer which has a principal surface on which a plurality of pixels are two-dimensionally arranged;
