PURPOSE:To obtain easily a complementary color image by forming a pair of linear polarizing films provided to a twisted nematic type liquid crystal display device in such a way that one thereof can rotate 90 deg.. CONSTITUTION:A twisted nematic type liquid crystal display device consists of a lower transparent base plate 1, a liquid crystal material 2, picture element electrodes 3, a common electrode 4, a color filter 5, an upper transparent base plate 6, a liquid crystal sealing part 7, a rear linear polarizing film 8, a front linear polarizing film 10, a transparent plate 9, a light diffusing plate 11, a light source 12 and a reflecting cover 13. The film 10 is so constituted that the film can rotate 90 deg. integrally with the plate 9. A complementary color image is easily obtd. by rotating 90 deg. the film 10 with the operation from the outside. |
