A liquid crystal display device of a transverse electric field type has characteristics in the following respects. A liquid crystal layer is sandwiched between two substrates. Two polarizing plates are provided on a side of the two substrates opposite to the liquid crystal layer such that the light transmission axes thereof are orthogonal to each other. A first electrode and a second electrode are formed on one of the two substrates. The liquid crystal is driven by an electric field generated between the first electrode and the second electrode. The polarizing plate, formed on one of the two substrates, is formed of a protective film, a polarizer, and two negative biaxial films. The two negative biaxial films include first and second negative biaxial films. The first negative biaxial film and the second negative biaxial film are entirely overlapped, and are disposed on a side of one or the other substrate.
