LAMINATE AND MANUFACTURING METHOD OF LIGHT-EMITTING ELEMENT EMPLOYING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a laminate on which dicing can be performed without damaging a light-emitting layer and which has an uneven structure for light extraction improvement, and a manufacturing method of a light-emitting element including the step of dicing the laminate.SOLUTION: The laminate includes: a substrate including the light-emitting layer; and a structure layer formed on a surface of the substrate closer to the light-emitting layer or on a surface opposite to the light-emitting layer. The structure layer includes: a structure zone; and a clearance path formed along a boundary line of an area where the structure zone is formed. The structure zone includes an uneven structure of which the height is 50 nm or more, on the surface thereof. Average mathematic roughness of a surface of the clearance path is more than 0 nm and less than 50 nm. The manufacturing method of the light-emitting element is also disclosed which includes the step of dicing the laminate.
