PROBLEM TO BE SOLVED: To obtain the liquid crystal display device which can make displays entirely on both the surfaces without using two liquid crystal display panels. SOLUTION: This device is equipped with a 1st reflecting polarizer 18 which is arranged on both the sides of one surface of a liquid crystal cell 22, a 2nd reflecting polarizer 42, which is arranged on the other surface side, a 1st absorption type polarizer 14 which is arranged on the external surface side of the 1st reflecting polarizer 18, a 2nd absorption type polarizer 46 which is arranged on the external surface side of the 2nd reflecting polarizer 42, and a light guide plate 52 which is arranged on the most external surface side between the sides of the liquid crystal cell. The 1st reflecting polarizer 18 reflects polarized light having a plane of polarization in a 1st reflection axis direction and transmits polarized light having a plane of polarization in a 1st transmission axis direction different from the 1st reflection axis direction. The 2nd reflecting polarizer 42 reflects polarized light in a 2nd reflection axis direction and transmits polarized light in a 2nd transmission axis direction different from the 2nd reflection axis direction. The 1st absorption type polarizer 14 has an axis of transmission nearly parallel to the 1st axis of transmission and the 2nd absorption type polarizer 46 has an axis of transmission nearly parallel to the 2nd axis of transmission. |
