Abstract
Objects are to provide a semiconductor device with a novel structure, to provide a semiconductor device with low power consumption, and to provide a semiconductor device with a small chip area. A digital-analog converter and a frame memory are included. The frame memory includes a sample-and-hold circuit, a correction circuit, and a source follower circuit. The sample-and-hold circuit retains the analog voltage output from the digital-analog converter. The correction circuit corrects the analog voltage retained in the sample-and-hold circuit. The source-follower circuit outputs the corrected analog voltage. The sample-and-hold-circuit, the correction circuit, and the source follower circuit each comprise a first transistor. The first transistor comprises an oxide semiconductor layer in a semiconductor layer.
