Abstract

A method of manufacturing a full-color organic EL panel in which pixels emitting light of different colors are formed by selectively depositing an organic material on a pixel-by-pixel basis, wherein, a deposition process of depositing an organic material for emitting light of at least one color includes a first step of depositing an organic material for emitting light of at least one color, using a first mask, on a first group of pixels corresponding to openings of the first mask, and a second step of depositing an organic material for emitting light of the same color as the one color, using a second mask, on a second group of the pixels corresponding to openings of the second mask.

Claims (1)

1. An organic electroluminescent panel comprising a plurality of pixels emitting light of a single color, the pixels being formed by selectively depositing an organic material, each pixel having a corresponding color purity and a corresponding luminous efficiency, wherein the color purity of a selected first pixel of the plurality of pixels is higher than the color purity of a selected second pixel of the plurality of pixels, and wherein the luminous efficiency of the selected first pixel is lower than the luminous efficiency of the selected second pixel.
