Abstract
A liquid crystal display device includes a liquid crystal panel having a plurality of pixels grouped into four types of type 1, type 2, type 3, and type 4; a panel driver circuit connected to the liquid crystal panel to drive the liquid crystal panel; and a display control circuit connected to the panel driver circuit, wherein said display control circuit divides each refresh cycle of the image signal into consecutive first to fourth terms and causes the panel driver circuit to drive the liquid crystal panel to perform a halftone display by changing pixel luminance during each refresh cycle composed of the first to fourth terms, and wherein said display control circuit provides timing signals and gradation data to the panel driver circuit so that, for a given halftone to be displayed in a refresh cycle, pixels belonging to respective types in the liquid crystal panel are driven such that the halftone is generated as averaged over the first to fourth terms.
