Abstract
A signal processing device which is used in a liquid crystal apparatus, includes a detection portion that detects a boundary between a first pixel to which a first voltage lower than a first reference voltage is applied and a second pixel to which a second voltage higher than a second reference voltage is applied on the basis of signals for controlling voltages applied to a plurality of pixels, and a correction portion that corrects the first voltage correlated with the first pixel to a third voltage which is higher than the first voltage and lower than the second voltage correlated with the second pixel.
