Abstract:
A semiconductor device or the like with low off-state current is provided. A semiconductor device or the like for displaying images accurately is provided. A display device or the like with a wide viewing angle is provided. A display device or the like in which image burn-in is suppressed is provided. In order to achieve any of the above objects, a circuit is formed using a transistor including an oxide semiconductor (OS), particularly a thin film MOS transistor including an oxide semiconductor. The oxide semiconductor is a substantially intrinsic semiconductor. Thus, the off-state current of the transistor is extremely low.
