Abstract
An organic photoelectronic device includes a first electrode and a second electrode facing each other, and an active layer between the first electrode and the second electrode and including a first compound represented by Chemical Formula 1 or 2, and a ratio between a FWHM of a light absorption curve depending on a wavelength of the first compound in a solution state and in a thin film state satisfies the following Relationship Equation 1: FWHM2/FWHM1<2.5. In the Relationship Equation 1, FWHM1 is a FWHM of the light absorption curve depending on a wavelength in a solution state, and FWHM2 is a FWHM of the light absorption curve depending on a wavelength in a thin film state.
