摘要:
A transmitting liquid crystal display apparatus includes a liquid crystal panel including a pair of substrates, a pair of polarizers arranged adjacent to the pair of substrates respectively, a liquid crystal layer held between the pair of substrates, and electrodes arranged on at least one of the pair of substrates and serving to apply an electric field to the liquid crystal layer; and a light source unit arranged external to the pair of substrates, in which each of the pair of polarizers has an absorption axis along with an extraordinary wave axis of molecules constituting the polarizers. In this apparatus, a dye layer having a disc-form molecular structure is arranged between the polarizer and the substrate, or adjacent to the polarizer in proximity to the viewer. The dye layer has a transmission axis along with the extraordinary wave axis of the disc-form molecular structure.
