A novel organic LEFET device with a simple device constitution is presented. The device is equipped with a diffraction grating that is formed on the gate insulator so that it is located outside the channel region. When the device is operated with square‐wave alternating gate voltages, the spectrally‐narrowed emissions are definitively observed with FWHM ∼2 nm.
