Abstract: A semiconductor device having a novel structure is provided. Fluctuation in the grayscale voltage due to an offset voltage is suppressed. When a current corresponding to a lower-bit grayscale voltage is generated in a transconductance amplifier, voltages VHI and VLO supplied to the transconductance amplifier are alternately input to two input terminals in accordance with a digital signal of the most significant bit of lower bits. Since a change corresponding to the offset voltage is added to both the maximum and minimum values of the current output from the transconductance amplifier, fluctuation in the grayscale voltage due to the offset voltage can be suppressed.
