    • The present invention provides an EL panel, an EL illumination device, and an EL display device in which irregularity of luminance does not easily occur in the in-plane of the EL element by a protection sheet for suppressing conduction of heat on the outermost surface of the EL element. There is 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. Irregularity of luminance in the in-plane of the EL element does not easily occur by optimizing the height of the apex and the distance between the apexes.
    • 本发明提供一种EL面板,EL照明装置和EL显示装置,其中,通过用于抑制EL元件的最表面上的热传导的保护片,EL元件的面内不容易发生亮度不均匀 EL元素。 EL面板包括:透光基板; EL元件,其包括介于阴极和阳极之间的发光介质层,所述EL元件设置在所述透光基板的一个表面上; 以及在EL元件的透光性基板的另一面的保护片。 保护片具有与透光基板相反的表面,该表面的形状包括圆形凸形和棱镜形状。 每个圆形具有顶点,该顶点是距离底部表面最远的横截面的中心点,其中横截面平行于单元凸形的底表面,并且该区域在从底部的方向上变小 圆形凸形的表面到其顶部。 通过优化顶点的高度和顶点之间的距离,EL元件的平面内的亮度的不均匀性不容易发生。
