METAL MASK

摘要

PURPOSE: A metal mask is provided to maintain constantly an interval between a transparent substrate and a metal mask and form an organic emission layer having a predetermined pattern by forming a plurality of magnetic projections on a surface of the metal mask corresponding to the transparent substrate. CONSTITUTION: A metal mask includes a plurality of projections(62). The projections(62) are formed on a predetermined position except a pattern region of a metal mask(60). A part of the projections(62) is formed with the magnetic material. The projections(62) are used by an evaporator having a plurality of magnetic generators. The magnetic generators are used for generating selectively the magnetic force or extinguishing selectively the magnetic force. The projections are selectively adhered to the evaporator according to the presence of the magnetic force of the magnetic generators.
