A signal processing device, on the basis of signals that control voltages to be applied to pixels, a boundary between a first pixel corresponding to a first signal that applies a first voltage and a second pixel adjacent to the first pixel and corresponding to a second signal that applies a second voltage different from the first voltage at least by a predetermined threshold. The first signal is corrected to a third signal that applies a third voltage higher than the first voltage, and the second signal is corrected to a fourth signal that applies a fourth voltage higher than the second voltage. The second voltage is higher than the first voltage, the fourth voltage is higher than the third voltage, and a potential difference between the first voltage and the third voltage is larger than a potential difference between the second voltage and the fourth voltage.

In the case where a gray-scale difference &#x394;1 between a pixeland a pixel, a gray-scale difference &#x394;2 between the pixeland a pixelare each larger than a threshold value, and &#x394;1&#x3e;&#x394;2, gray-scale values of the pixelsandare corrected into the gray-scale value of the pixel+&#x394;1&#xd7;(1&#x2212;&#x3b1;), the gray-scale value of the pixel+&#x394;2&#xd7;(1&#x2212;&#x3b1;), and the gray-scale value of the pixel+&#x394;2&#xd7;&#x3b2;, respectively (0&#x2266;&#x3b1;, &#x3b2;&#x2266;0.5). After the correction, a gray-scale different &#x394;1a between the pixelsand, and a gray-scale different &#x394;2a between the pixelsandsatisfy the following formulas: &#x394;1a&#x3e;&#x394;1, and &#x394;2a&#x3e;&#x394;2, respectively.
