Abstract:
A liquid crystal display panel (100) according to an embodiment includes: a first polarizer (22) and a first phase plate (32) on the viewer's side; and a second polarizer (24) and a second phase plate (34) on the rear face side. A liquid crystal layer, which takes a homogeneous alignment in the absence of an applied electric field, has a Δnd of not less than 360 nm and not more than 490 nm; a retardation R1 of the first phase plate is not less than 100 nm and not more than 160 nm; and a retardation R2 of the second phase plate is not less than 200 nm and not more than 360 nm. The slow axes of the first and second phase plates are substantially parallel to each other and substantially orthogonal to the azimuth direction of the director of the liquid crystal.
