Abstract
A two-dimensional organic thin film electroluminescence (EL) display unit has a plurality of one-dimensional organic EL arrays extending in a first direction and adhered together in a second direction perpendicular to the first direction. The EL array has a transparent substrate having a main surface directed to the second direction, and a multilayer EL structure formed on the main surface and including a plurality of first layer transparent electrodes extending perpendicular to the array, an organic EL thin film and a second layer metallic electrode extending along the array. The EL array emits luminescence in the third direction perpendicular to the first and second directions. The first layer electrodes and the second layer electrode drive the EL array in a matrix drive. The organic EL display unit exhibits excellent image quality, contrast and brightness.
