Light emitting device with selection circuit for image signal polarity inversion

摘要

A light-emitting device capable of displaying an image using image signals having different polarities is provided. The light-emitting device includes a first circuit holding a first image signal having a first polarity, a second circuit holding a second image signal having a second polarity different from the first polarity and converting the second polarity of the held second image signal into the first polarity, and a light-emitting element whose luminance is sequentially determined in response to the first image signal held in the first circuit and the second image signal whose polarity is converted into the first polarity in the second circuit.
