It is used to delay the phase of the polarized light and convert it into another axially polarized light. For example, in order to display the same polarized light on both sides, the s-polar light reflected by the reflective polarizing film can be converted into p-polarized light by the retardation of the phase retardation film 45, and the second liquid crystal display panel 41 is used. The phase delay film 45 can be a 1/4 wavelength phase retardation film. As shown in FIG. 7 , the erected ytterbium ytterbium is an optically rotative selective film, which allows a first rotatory light to penetrate and reflect a first light. Here, the liquid crystal display device 4 of the embodiment may further comprise The one-phase retardation film 44 is disposed between the reflective polarizing film 43 and the first liquid crystal display panel, and is a reflective polarizing film 43 that allows only right-handed light to pass therethrough. For example, the light transmitted to the first liquid crystal display panel 4 via the light guide plate 421 is a mixed light including a left-handed light and a right-handed light, and when the reflective polarized light is allowed to be right-handed (four), the left-handed turn is reflected. The right-handed light continues to be converted into a polarized light such as p-polarized light as the surface light source of the display panel 40, and the left-handed j 14 1359996 reflected by the reflective polarizing film q can be further supplied to the second liquid crystal. The display panel 41 is used. As described above, in order to achieve different display purposes, the present embodiment may further provide another phase-expanding film between the second liquid crystal display panel q and the light guide plate 421 to cause left-handed light reflected by the reflective polarizing film 43. The delay and conversion into phase to form p-polarized light 'and the matching of the polarizing plate 4 '' disposed on both sides of the liquid crystal display panels 4, 41 achieve the purpose of double-sided display. Among them, the reflective polarizing film 43 may be, for example, a -cholesterol liquid crystal (liquid crystal y CLC) brightening enthalpy, and a phase retardation film 44 wavelength retardation film. In the present embodiment, the liquid crystal display device 4 may further include a diffusion sheet 46 disposed on one side of the phase retardation film 45 for enhancing the uniformity of light. However, the liquid crystal display device 4 of the present embodiment may further include another reflective polarizing film disposed between the light guide plate 421 and the phase retardation film 45 (not shown) to enhance the utilization efficiency of light.
