<P>PROBLEM TO BE SOLVED: To provide a liquid crystal display device capable of preventing the occurrence of moire while suppressing a deterioration of front brightness. <P>SOLUTION: The liquid crystal display device 1 includes a surface light source 4, a liquid crystal display panel 2, and first and second prism sheets 5 and 6 which keep prism array directing at right angles and collect the light outputted from the surface light source 4 and guide it to the liquid crystal display panel side, and is configured in a manner to satisfy the relationships of Px≤Pp/(14-0.045Pp) and Py≤Pp/(11.5-0.032Pp) where Pp (μm) is the pixel pitch of the liquid crystal display panel 2, Px (μm) is the prism array pitch of the first prism sheet 5, and Py (μm) is the prism array pitch of the second prism sheet 6. <P>COPYRIGHT: (C)2008,JPO&INPIT |
