ABSTRACT:
A highly fine organic electroluminescent device is provided. A method for manufacturing the organic electroluminescent device is provided for patterning a very fine light emitting layer, and a deposition mask is provided to be used in the patterning. For deposition of the light emitting layer, a mask member is provided with apertures (effective apertures) for forming the light emitting layer to be used for light emitting pixel and apertures (dummy apertures) not to be used for forming the light emitting pixel around an area (effective aperture area) separated by the outer edge of a group of the apertures. The light emitting layer is deposited by using the deposition mask.
