Abstract:
An organic electroluminescent element includes electrodes and organic light-emitting layers that are between the electrodes. The organic light-emitting layers contain at least three colors of luminescent materials. A first luminescent material has a maximum light emission wavelength within a range of 430 nm to 480 nm. A second luminescent material has a maximum light emission wavelength within a range of 510 nm to 610 nm. A third luminescent material has a maximum light emission wavelength within a range of 580 nm to 630 nm. An average value of average color rendering indexes in a wide angle region of 30° to 60° with respect to a front direction of a light emission surface is higher than an average color rendering index in the front direction.
