An image projection apparatus comprises an illumination unit (10), an image display unit (20), comprising a matrix display panel (22) having a row and column array of pixels (25), a projection lens (40) for projecting range produced by the display panel on to a screen (50) and an optical deflection unit (30) arranged between the display unit and the projection lens which is operable selectively to shift the light rays from a row of pixels passing therethrough whereby the pixel row images on the screen in one field are displaced and interlaced with the pixel row images of a preceding field. The image display unit (20) includes an array of lens elements (60) overlying the array of pixels whose effect is to reduce the height of the image of each pixel row in the projected display so the pixel row images of one field can fill the gaps between adjacent pixel row images of a preceding field without any substantial overlap and display panels having high aperture ratio can be utilised.
