Abstract
A signal processing device for supplying a drive voltage signal to a display panel, includes a luminance detector, a memory to store a first correction factor for correcting the luminance level of the pixel to be changed by a voltage level difference between a drive voltage signal supplied to the display element and a drive voltage signal supplied to a first adjacent display element adjacent to the display element in the forward direction of the scanning line, and a second correction factor for correcting the luminance level of the pixel to be changed by a voltage level difference between a drive voltage signal supplied to the display element and a second adjacent display element adjacent to the display element in the reverse direction of the scanning line, a correction voltage level computing unit, and an adder to add the first correction voltage level and the second correction voltage level.
