1. A signal processing device, for use with a liquid crystal device including a plurality of pixels, the signal processing device comprising a signal processing unit that processes a signal that controls a gray scale level that is displayed at each of the plurality of pixels for each frame, wherein:
with respect to a first pixel that displays a first gray scale level lower than a first reference gray scale level, and which is adjacent to a pixel that displays a gray scale level higher than a second reference gray scale level, the signal processing unit corrects so as to display a gray scale level that is higher than or equal to the first reference gray scale level and lower than the second reference gray scale level, and
the correction is performed by the signal processing device based upon detection of the first gray scale level and the first pixel.
