This abstract first appeared for US patent application 20250143014 titled 'METHOD FOR MANUFACTURING DISPLAY DEVICE
Original Abstract Submitted
a method for manufacturing a display device includes manufacturing an epitaxial wafer including an epitaxial thin film, dividing the epitaxial wafer into wafer dies having a size corresponding to an area of each cell area of a backplane substrate including cell areas, transferring the wafer dies to a carrier substrate, forming a conductive bonding layer on epitaxial dies of the wafer dies, disposing the carrier substrate on the backplane substrate such that the epitaxial dies are disposed in each cell area of the backplane substrate and bonding the epitaxial dies onto the backplane substrate, removing the carrier substrate from the epitaxial dies, and etching the epitaxial dies to form respective light emitting elements in emission areas included in each cell area of the backplane substrate.
