Abstract
LCD color television front projection screen has a rear vertically oriented lenticular lens array, the sidewalls of the lenticules steeply inclined to achieve total internal reflection of rays from a projected image into tip regions of the lenticules, an external reflective surface behind the array for reflecting the projected rays back into an audience field in front of the screen, and black masking between the lenticules for absorbing ambient rays.
