An organic light-emitting device including a first substrate, a second substrate, a light drawing-out layer disposed between the first substrate and the second substrate, a transparent electrode disposed between the light drawing-out layer and the first substrate, a reflection electrode disposed between the transparent electrode and the first substrate, and a first light-emitting unit disposed between the transparent electrode and the reflection electrode. The first light-emitting unit includes a first light-emitting layer that emits a first light-emitting color. In the organic light-emitting device, relations of the equation L1≧λ2/4 and the equation L1 cos θ1=λ1 (¼+n/2) are satisfied, wherein L1 is an optical length from a light-emitting point in the first light-emitting layer to the reflection electrode, λ2 is a wavelength at the longer wavelength side, having an intensity of 1% of the maximum intensity of a light-emitting spectrum of the first light-emitting color, λ1 is a wavelength at the shorter wavelength side, having an intensity of 1% of the maximum intensity of the light-emitting spectrum of the first light-emitting color, n is an integer not less than 0, and 0<θ1≰60. |
