METHOD OF MANUFACTURING CIRCUIT BOARD, METHOD OF MANUFACTURING LIGHT-EMITTING DEVICE, AND LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To manufacture a circuit board that suppresses damage to an electrode, or to manufacture a light-emitting device that suppresses damage to an electrode.SOLUTION: A method of manufacturing a circuit board or a light-emitting device includes a step of preparing a processing member that includes a circuit and a terminal electrode on a first substrate, a separation layer on the terminal electrode, an adhesive layer on the separation layer, and a second substrate on the adhesive layer, performing cutting processing by using a blade that enables cutting processing by rotation to form a groove part on the processing member, and removing a part of the separation layer, the adhesive layer, and the second substrate so as to expose a part of the terminal electrode.SELECTED DRAWING: Figure 1
