White light emitting organic el panel and method for producing same

A white light-emitting organic EL panel comprising an organic EL element that includes:

• an anode layer;
• a cathode layer;
• and
• a light-emitting functional layer between the anode layer and the cathode layer,
• the light-emitting functional layer including in order from the anode layer toward the cathode layer:
• an anode side blue light-emitting unit;
• a connection layer;
• and a cathode side red-green light-emitting unit,
• the connection layer injecting electrons into the anode side blue light-emitting unit and injecting holes into the cathode side red-green light-emitting unit when current is applied,
• the cathode side red-green light-emitting unit including a red-green phosphorescent light-emitting layer that is a single composite layer including:
• a red color phosphorescent material;
• a green color phosphorescent material;
• and
• a host material for the phosphorescent light-emitting layer,
• wherein maximum emission peak wavelength of the red color phosphorescent material is apart from maximum emission peak wavelength of the green color phosphorescent material by 60 nm or more, and
• wherein the white light-emitting organic EL panel is capable of emitting white light with an general color rendering index Ra and a special color rendering index R9 in accordance with JIS Z 8726, both of the Ra and the R9 being greater than or equal to 90.
