STRUCTURE OF ORGANIC MATERIAL EVAPORATING BOAT FOR APPARATUS FOR MANUFACTURING ORGANIC ELECTROLUMINESCENCE DISPLAY

摘要

PURPOSE: A structure of organic material evaporating boat is provided to obtain an organic material layer having a uniform film thickness by evaporating, to the substrate, the host organic source and dopant organic source through the evaporation holes. CONSTITUTION: A structure comprises a plurality of host cells(42) having a plurality of evaporation holes for evaporation of a host organic source; a plurality of dopant cells(44) disposed alternately with the host cells, and which have a plurality of evaporation holes(46) for evaporation of a dopant organic source; a contamination prevention plate interposed between the host cells and the dopant cells; and a side cover(50) for covering the host cell and the dopant cell. Each of the host cells and the dopant cells includes a cell body for evaporation of organic source; a heater coil wound along the periphery of the cell body; and a cap having evaporation holes.
