PURPOSE:To easily and optically compensate the defect of a picture element of a liquid crystal panel by arranging a defective picture element compensating element which guides part of light transmitted through a nearby picture element to the transmitted light path of the defective picture element in front of the defective picture element. CONSTITUTION:A defective picture element compensating element 41 which is arranged in front of the defective picture element 12b is interposed between a glass plate 27 and a polarizing plate 31, fixed on the top surface of the glass plate 27, and equipped with a couple of light guiding-in parts 42 provided across the defective element 12b. The incidence end surface 43 of the light guiding-in part 42 faces part of adjacent picture elements 21a and 12c and a part of projection light from the picture elements 12a and 12c is made incident on the light guiding-in part 42; and one light beam I is reflected by total reflecting surfaces 44 and 45, transmitted through the polarizing plate 31 from a projection end surface 46, and projected out. The light beam II is similarly transmitted through the polarizing plate 31 and projected out, and the projected light beams I and II seem to have passed through the defective picture element 12b. Thus, the light transmitted through normal picture elements 12a and 12c on both the sides of the defective picture element 12b is guided to the defective picture element 12b to compensate the defect. |
