LIQUID CRYSTAL DISPLAY DEVICE

摘要

Provided is a liquid crystal display device capable of preventing generation of moiré while suppressing lowering of the front face luminance. The liquid crystal display device (1) includes a planer light source (4), a liquid crystal display panel (2), and a first and a second prism sheet (5, 6) in which the prism arrangement directions orthogonally intersect for collecting light emitted from the planar light source (4) and introducing the light to the liquid crystal display panel. When the liquid crystal display panel (2) has a pixel pitch Pp [µm], the first prism sheet (5) has a prism arrangement pitch Px [µm], and the second prism sheet (6) has a prism arrangement pitch Py [µm], the following relationships are satisfied: Px = Pp/(14 -0.045 Pp) and Py = Pp/(11.5 - 0.032 Pp).
