Abstract:
1. An electro-optical device comprising: a display unit that has a plurality of pixel portions; and an image signal processing circuit that generates, for a first pixel portion of the plurality of pixel portions, a first image signal and a second image signal, the first pixel portion including a pixel electrode and a thin-film transistor for switching on and off the pixel electrode, the first pixel portion having a luminance difference between an n-th frame and an m-th frame, a difference between the m and n being one, the luminance difference being greater than or equal to a predetermined threshold, the first image signal setting a luminance of the first pixel portion in a first subframe of the m-th frame higher than a first frame luminance, the first frame luminance being a luminance to be displayed in the first pixel portion in the m-th frame by an original image signal, the second image signal setting a luminance of the first pixel portion in a second subframe of the m-th frame lower than the first luminance, wherein the image signal processing circuit includes: a color image signal including red, green and blue color component signals is supplied to the image signal processing circuit, the comparator is provided for each of the red, green, and blue color component signals included in the color image signal, and in the case that the difference between the first frame luminance and the second frame luminance of at least one of the red, green, and blue color component signals is greater than or equal to the predetermined threshold, the image signal processing circuit setting the luminance of the first subframe and the luminance of the second subframe to the first pixel portion regarding all the red, green, and blue color component signals.
