Abstract

A liquid crystal display device includes a liquid crystal layer which is arranged between first and second aligning films formed on inner sides of first and second substrates, has liquid crystal molecules twist-aligned in a direction from the first aligning film toward the second aligning film when an electric field is not applied between first and second electrodes, and generates retardation of substantially λ/2 with respect to transmitted light. First and second polarizing plates are arranged on outer sides of the first and second substrates. A Transmission axis or an absorption axis of the first polarizing plate is substantially matched with a direction along which the liquid crystal molecules in the vicinity of the first aligning film are aligned when a sufficiently intensive electric field is applied.
