摘要:
The organic electroluminescence display apparatus of the present invention comprises a first and second substrates, the former being coated with banks for separating pixels, a lower electrode, organic light-emitting layer and upper electrode of a transparent material in this order, and the latter being coated with a color filter and electroconductive shadow pattern, wherein the organic light-emitting layer surrounded by the banks for separating pixels faces the color filter, and the first and second substrates face each other in such a way that the upper electrode over the banks for separating pixels is electrically connected to the electroconductive shadow pattern. This structure connects at least one of the upper electrode and electroconductive shadow pattern to a power supply point, to control ununiform emitted light brightness which may result from voltage drop at the upper transparent electrode. Moreover, the organic light-emitting layer can be formed without a vapor deposition mask having a precise aperture pattern, to efficiently produce the organic EL display apparatus.
