Patent attributes
A display element including a layer with a protrusion-recess structure and a multilayer film layer disposed on the protrusion-recess structure and with a surface shape following the protrusion-recess structure. A pattern formed by the protrusion includes a plurality of shape elements when the protrusion-recess structure is viewed in a direction perpendicular to the surface. Each shape element has a length extending in one extending direction, larger than a length in a width direction perpendicular to the extending direction. The length in the width direction is equal to or less than a sub-wavelength. A standard deviation of the length in the extending direction is larger than a standard deviation of the length in the width direction. The display elements include a first display element and a second display element. The extending directions of the first display element and the second display element are different from each other.
