Abstract
A display panel is the one in which a pixel composed of sub-pixels of red (R), green (G), blue (B), and at least one other color has two sub-pixels at least in a vertical scanning direction, and color filters are provided respectively corresponding to the sub-pixels. There are provided: an incoming signal interpolating section which interpolate each of pixels based on incoming color signal components of red (R), green (G), and blue (B) at least in a vertical scanning direction to generate interpolated RGB signals; a luminance signal converting section which converts color signals of interpolated sub-pixels, which are obtained from the incoming signal interpolating section, into luminance signals; an another color luminance component adding section which adds a luminance signal component of at least one other color on a basis of luminance signal components of colors of red (R), green (G), and blue (B), which components are outputted from the luminance signal converting section; and a luminance reallocating section which reallocates luminance signals of peripheral interpolated sub-pixels, for a color of each of the color filters corresponding to the sub-pixels, in accordance with output from the another color luminance component adding section.
