Abstract

PURPOSE:To allow the viewer to enjoy a television magnified picture with a very inexpensive system by constituting the system with a transmission type TFT active matrix liquid crystal color display element, back light source, an expanding lens system and a projection screen. CONSTITUTION:The light from light sources 8, 9 is given to the transmission type TFT active matrix liquid crystal color display elements 6, 7 via an optical diffusion plate 10 and projected on a screen 13 via magnification lenses 11, 12. Since it is meaningless if two display bodies pick up the entirely identical picture, the display is shared by separating the television signal into one interlace and the other and displayed pictures are overlapped while being more or less shifted so as to produce the interlace effect on the screen 13.
