た。<Example> As shown in Fig. 3, a high color rendering type fluorescent lamp made into an aperture type with peaks in three primary colors was used as the light source 1, and the liquid crystal panel had a 12-shutter/mi-IJ, A pseudo time division drive was adopted. The color filter was determined so that its spectral distribution corresponded to the three peaks in Figure 3, and was screen printed on glass, afterbaked, and dyed. A film was deposited on top of the liquid crystal panel, and the liquid crystal panel 3 was produced using the same method as for manufacturing a normal liquid crystal panel. used.
さらに、パルス数変調回路を加え、各色８階ＮｌＡｌの
