Method of manufacturing organic EL element, organic EL element, and organic EL display device

An organic EL device manufactured via a nozzle, comprising:

• a substrate;
• first electrodes provided on or above the substrate;
• at least one luminescent layer, each of which has a certain color and is made of an organic compound, the luminescent layers being formed above the first electrodes by patterning by means of an ink-jet system, the formation of the at least one luminescent layer being performed by discharging a luminescent material composition from the nozzle toward the substrate, the luminescent material composition serving as luminescence function and carrier transfer function in the formed at least one luminescent layer;
• and
• a second electrode formed on or above the luminescent layers.

A method of manufacturing an organic EL device, comprising:

• forming first electrodes on or above a substrate;
• forming three types of luminescent layers on or above said first electrodes by patterning, each of said luminescent layers having a certain color and made of an organic compound;
• and
• forming a second electrode opposing the first electrodes,
• the formation of the at least two types of the luminescent layers being performed by means of an ink-jet method, the ink-jet method including discharging a luminescent material composition from a nozzle toward the substrate, the luminescent material composition serving as luminescence function and carrier transfer function in the formed at least two types of luminescent layers.

A method of manufacturing an organic EL device, comprising:

• forming first electrodes on or above a substrate;
• forming a first luminescent layer having a first color and made of a first organic compound above first predetermined first electrodes by an ink-jet method and
• forming a second electrode opposing the first electrodes,
• the formation of said first luminescent layer by means of the ink-jet method being performed by discharging a luminescent material composition from a nozzle toward the substrate, the luminescent material composition serving as luminescence function and carrier transfer function in the formed first luminescent layer.

An organic EL device manufactured via a nozzle, comprising:

• a substrate;
• first electrodes provided on or above the transparent substrate, said first electrodes include first first electrodes, second first electrodes and third first electrodes that are arranged in a predetermined order;
• first, second and third luminescent layers respectively formed on or above the first, second and third predetermined first electrodes, in which said first, second and third luminescent layers have first, second and third colors, respectively, and are made of first, second and third organic compounds, respectively, at least the first luminescent layer formed above the first first electrodes by patterning by means of an ink-jet system, the formation of the first luminescent layer being performed by discharging a luminescent material composition from the nozzle toward the substrate, luminescent material composition serving as luminescence function and carrier transfer function in the formed first luminescent layer;
• and
• a second electrode formed on or above the luminescent layers.
