Abstract

A display apparatus having an excellent boosting function is provided. The display apparatus is provided with a pixel having a function of adding data (a boosting function). A capacitor for boosting voltage is provided in the pixel, and data is added by capacitive coupling to be supplied to a display device. The capacitor for boosting voltage and a capacitor for retaining data are placed on top of each other, whereby the capacitance value of the capacitor for boosting voltage can be increased. Thus, the pixel can have an excellent boosting function, without significantly losing the aperture ratio or definition.
