ABSTRACT:
To provide an organic EL device which is capable of forming a minute optical resonator in a light-emitting element and improving the chromaticity of color light components to be emitted, without complicating a manufacturing process, a method of manufacturing the organic EL device, and an electronic apparatus. In an organic EL device1, each element comprises an anode4and a first insulating layer10a, a light-transmitting layer13having a refractive index larger than that of a transparent substrate2, a cathode7having light reflection which oppose a transparent electrode4, and an organic functional layer including a light-emitting layer6and a hole injecting layer5. In green color light-emitting elements, a first optical length, which is the sum of the product of film thickness and refractive index of the hole injecting layer and the product of film thickness and refractive index of the light-emitting layer, is 250 nm or less, and in blue color light-emitting elements, a second optical length, which is the sum of the product of film thickness and refractive index of the hole injecting layer and the product of film thickness and refractive index of the light-emitting layer, is 230 nm or less. A third optical length, which is the product of film thickness and refractive index of the light-transmitting layer13, is 300 nm or less.
