LIGHT-EMITTING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light-emitting device in which a separation layer is transcribed without damaging the separation layer and the like and without irradiation with a laser beam with relatively high output.SOLUTION: In a light-emitting device in which a separation layer is transcribed to a plastic substrate provided with a barrier film, metal oxide remains selectively on the plastic substrate. The metal oxide remains after separation performed following heat treatment on the separation layer on the glass substrate.
