ABSTRACT:
A liquid crystal display apparatus is provided in which occurrence of a moiré pattern can be prevented without largely reducing front luminance. A liquid crystal display apparatus1includes a surface light source4, a liquid crystal display panel2, and first and second prism sheets5and6for condensing light emitted from the surface light source4and guiding the light toward the liquid crystal display panel. The first and second prism sheets5and6are disposed such that prism array directions thereof are orthogonal to each other. When a pixel pitch of the liquid crystal display panel2is defined as Pp [μm]; a prism array pitch of the first prism sheet5is defined as Px [μm]; and a prism array pitch of the second prism sheet6is defined as Py [μm], relationships of Px≦Pp/(14−0.045 Pp) and Py≦Pp/(11.5−0.032 Pp) are satisfied.
