Abstract
Objects are to provide a semiconductor device with a novel structure, to provide a semiconductor device with high resistance to noise, to provide a semiconductor device with a small chip area, and to provide a semiconductor device with low power consumption. In a memory cell included in a frame memory, a transistor containing an oxide semiconductor and a transistor containing silicon are used in combination to retain charge, whereby data is retained. In this structure, turning off the transistor containing an oxide semiconductor can prevent data fluctuations even if power noise through a wiring is generated.
