要約
(EN)
The objective of the present invention is to provide a liquid crystal display device which has excellent color reproducibility. A liquid crystal display device according to the present invention comprises a non-white light source, a rear-side polarizer, a liquid crystal cell and a front-side polarizer in this order. This liquid crystal display device also comprises a light conversion layer, which performs wavelength conversion of light that has transmitted through the front-side polarizer, at a position closer to the viewing side than the front-side polarizer.

La présente invention concerne la fourniture d'un dispositif d'affichage à cristaux liquides qui a une excellente reproductibilité de couleur. Un dispositif d'affichage à cristaux liquides selon la présente invention comprend une source de lumière non blanche, un polariseur côté arrière, une cellule à cristaux liquides et un polariseur côté avant dans cet ordre. Ce dispositif d'affichage à cristaux liquides comprend également une couche de conversion de la lumière, qui réalise une conversion de longueur d'onde de la lumière qui a été transmise à travers le polariseur côté avant, en une position plus proche du côté de visualisation que le polariseur côté avant.
