Abstract
Output signals of a shift register in which latch circuits are connected in a plurality of stages are branched into two paths, NAND circuits are provided at the respective branched paths, and a sampling switch is turned on based on the output signals to sample an image signal into a data line. However, in response to the NAND circuit arranged at the left-branched path of the two path of a signal output by the first stage and the NAND circuit arranged at the right-branched path of the two path of a signal output by the last stage, neither the sampling switches nor the data lines are provided. With this, degradation of display quality is suppressed.
