A projection-type display device having a liquid crystal panel is provided which is capable of correcting for distortions in horizontal and vertical directions even when the liquid crystal panel is placed in a position other than such a position that the liquid crystal panel is right opposite to the screen. To display a video for correcting for distortions on a liquid crystal panel, location data of a video signal to be output to the liquid crystal panel is stored in advance into an address storing memory as address data of a frame memory. Address data of the frame memory being stored in the address storing memory is read in synchronization with a timing signal and, based on a result from the reading, a video signal is read from a corresponding address of the frame memory and a video based on the video signal is displayed on the liquid crystal panel. Thus, by displaying the video for correcting for distortions on the liquid crystal panel, correction for distortions can be achieved.
