ロジエクタ。 In a liquid crystal projector that projects a display image of a liquid crystal display panel onto a screen surface, a first display panel group consisting of three liquid crystal display panels that displays images whose horizontal pixel spacing is approximately equal to the width of one pixel. and an image whose horizontal pixel interval is approximately equal to the width of one pixel and which is shifted by one pixel width in the horizontal direction with respect to the display image of each liquid crystal display panel of the first display panel group is displayed. and a second display panel group consisting of three liquid crystal display panels, and among the liquid crystal display panels of the first group and the second group, the first liquid crystal display panel is used to display an image of the red component of the full-color image. The second liquid crystal display panel is a red image display panel that displays a green component image, and the third liquid crystal display panel is a blue image display panel that displays a blue component image. At the same time, the display images of each display panel of the first group and the second group are projected onto the screen surface to display the red color of each display panel of the first group,
A full-color pixel in which green and blue display pixels overlap and a full-color pixel in which red, green and blue display pixels of each display panel of the second group are arranged alternately in the horizontal direction are formed on the screen surface. A liquid crystal projector characterized by comprising an optical projection means for projecting an image.
