Abstract: An EL element including an EL light-emitting structure including a light-emitting layer on a transparent electrode, and a counter electrode on the light-emitting layer, a translucent substrate, and a light scattering layer between the EL light-emitting structure and the translucent substrate, the light scattering layer having a first surface on a transparent electrode side and a second surface on a side of the translucent substrate. The light scattering layer includes light scattering particles which includes particles that form agglomerates in a portion of the first surface such that the portion of the first surface has a concavo-convex shape. The light scattering particles further include particles positioned in order along the second surface such that the second surface is smoother than the portion of the first surface having the concavo-convex shape.

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.
