Filed: 1990-04-05
Abstract: PURPOSE:To increase apparent resolution and to make a display screen in a large scale by dividing green light into two, and projecting divided two beams of green light shifting by a prescribed gap. CONSTITUTION:Liquid crystal panels 5R, 5B, and 5G and a liquid crystal panel 5g are provided in such a way that the picture elements DR, DB, and DG of the panels 5R, 5B, and 5G are shifted by 1/2 picture elements from the picture element Dg of the panel 5g in a horizontal direction and a vertical direction, respectively. Therefore, a color image can be displayed on a screen 14 by projecting light WM from a lens 13, however, in such a case, since the picture element Dg is shifted by 1/2 picture elements in the horizontal and vertical directions, respectively from the picture elements DR, DB, and DG, the apparent number of picture elements in the horizontal and vertical directions can be doubled, which doubles the resolution. In such a way, since the apparent resolution can be increased, the display screen can be made in a large scale.
