  • Publication number: 20160116646
    Abstract: A liquid crystal display device 10 includes a liquid crystal panel 11 and a second light diffusing sheet 43 that is an anisotropic optical member. The liquid crystal panel 11 includes a display surface DS for displaying images. The liquid crystal panel 11 has anisotropy in an exit angle distribution of rays of exiting light such that an exit angle range of the exiting light is relatively small with respect to the first direction along the display surface DS and relatively large with respect to the second direction along the display surface DS and perpendicular to the first direction. The second light diffusing sheet 43 is disposed over the liquid crystal panel 11 on any one of the display surface DS side and an opposite side thereof. The second light diffusing sheet 43 has anisotropy in an exit angle distribution of exiting light such that an exit angle range of the exiting light is relatively large with respect to the first direction and relatively small with respect to the second direction.
