Abstract
A liquid crystal projector for projecting original images formed on a liquid crystal panel onto a screen comprises optical means 3 between the liquid crystal panel 2 and the screen 4. The optical means 3 has a first refracting portion comprising planar glass plates 3a, 3c having a predetermined angle of inclination with respect to the optical axis of the panel, and a second refracting portion comprising planar glass plates 3b, 3d having an angle of inclination different from that of the first refracting portion. The position where an image is formed by the first refracting portion on the screen is shifted from the image forming position for the second refracting portion by a small amount corresponding to the pitch of picture elements on the screen to form projected images of improved quality.
