Method for forming flat-structured electrode for passive matrix type organic LED display, involves setting steep slope angle of side walls of recess to provide electrical isolation for layer and deposited layer to form electrode

摘要

The method involves providing layer (3) made of thick-film process printable material in surface of a substrate (4). The thickness of printable material made layer is maintained from 50 nm-20 microns. The grave shaped recess (5) is formed in printable material made layer after a material removal is performed with respect to laser beam. The steep slope angle of the side walls of the recess is set to provide electrical isolation for deposited layer (2) and printable material made layer for forming electrode.
