PROBLEM TO BE SOLVED: To provide a blanket and a manufacturing method of a polymer EL element capable of uniformizing thickness of a polymer luminescent medium layer, and of ensuring surface flatness thereof. SOLUTION: In relation to a blanket used in printing polymer EL material ink, this blanket is characterized by that ten-point average roughness Rz of a surface is below 2μm or arithmetic average roughness Ra is below 0.2μm. This manufacturing method of a polymer EL element is characterized by printing polymer EL material ink by using the blanket. COPYRIGHT: (C)2006,JPO&NCIPI
