Abstract: A subwavelength grating displaying a colored image exhibiting a color corresponding to a grating period of a subwavelength grating in reflection directions including a specular reflection direction. A relief surface displaying a reflection image in monochromatic reflected light in reflection directions including a direction different from the specular reflection direction. An optical element has a first state in which neither a colored image nor a reflection image is displayed, a second state in which the colored image is mainly displayed, and a third state in which the reflection image is mainly displayed. A plane in which the optical element is disposed and a plane including a line of sight of an observer form an observation angle therebetween. The optical element is observed in any of the first, second and third states according to the observation angle.

Abstract: An EL panel including: a light-transmissive substrate; an EL element including a light-emitting medium layer interposed between a cathode and an anode, the EL element being provided on one surface of the light-transmissive substrate; and a protection sheet on the other surface of the light-transmissive substrate of the EL element. The protection sheet has a surface opposite to the light-transmissive substrate, the shape of the surface includes rounded convex shapes and prism shapes. Each of the rounded shapes has an apex that is a center point of a cross-section farthest from a bottom surface where the cross-section is parallel to the bottom surface of the unit convex shape and the area becomes smaller in a direction from the bottom surface of the rounded convex shape to a top portion thereof.
