Abstract
A highly reliable display apparatus is provided. In an EL display apparatus including a specific pixel having a function of adding data, a storage node is provided in the pixel, and first data can be held in the storage node. In the pixel, second data is added to the first data through capacitive coupling, whereby third data can be generated. A light-emitting device operates in accordance with the third data. In the pixel, a light-emitting device that requires a high voltage for light emission or a light-emitting device to which application of a high voltage is preferred is provided.
