Abstract
A liquid crystal display device () according to the present invention comprises: a transparent-display-area extraction circuit () for extracting an area to be used as a transparent display area from an input image signal (Sin); a subfield generation circuit () which divides the input image signal (Sin) into a plurality of subfields to generate a subfield image signal (Ssf) and reads, from a resister (), transparency setting data (Dts) for forcibly changing the transparent display area to a state of transparent display in all the subfields; and a display panel drive unit () which displays an image on a crystal liquid panel () for each subfield on the basis of the subfield image signal (Ssf) and changes the transparent display area into a state of transparent display on the liquid crystal panel () on the basis of the transparency setting data (Dts).
