Abstract
An electronic device includes: a TFT liquid crystal panel; a light source that emits light to be radiated onto a back face of the TFT liquid crystal panel; and a processor that generates a common signal to be input to a common electrode of the TFT liquid crystal panel. The processor generates the common signal so as to have a waveform that differs between when the light source is not lit and when the light source is lit.
