Abstract: A method of fabricating an organic EL display apparatus includes: obtaining a representative current (I)-voltage (V) characteristic of a display panel including pixels each having an organic EL device and a driving transistor; dividing the display panel into a plurality of divided regions, and calculating a light-emitting efficiency and an offset luminance value for each of the divided regions calculated by an I-luminance (L) characteristic of the divided region; measuring luminance of light emitted from each of the pixels and calculating an L-V characteristic of each of the pixels; calculating an L-V characteristic of each divided region by dividing each current value of the representative I-V characteristic by light-emitting efficiency, and by adding an offset luminance value; and calculating a correction parameter for each pixel such that the L-V characteristic of each pixel is corrected to the L-V characteristic of the divided region including the pixel.
