(JA) 液晶表示装置
Abstract: front page image
(EN)In a liquid crystal display device which uses a white LED as the light source, in order to avoid/suppress the reduction in the speed of response of the liquid crystal while increasing the color reproducibility and red chromaticity without the use of a special purpose color filter, a band cut filter (5) which absorbs the wavelength component neighboring orange in light that is transmitted is provided between the liquid crystal display (1) and the backlight unit (2).
(FR)Dans un dispositif d'affichage à cristaux liquides qui utilise une LED (Diode électroluminescente) blanche en tant que source lumineuse, pour éviter/supprimer la diminution de la vitesse de réponse du cristal liquide tout en augmentant la reproductibilité des couleurs et la chromaticité du rouge sans utiliser de filtre coloré spécialisé, on dispose un filtre coupe-bande (5) absorbant la composante de longueur d'onde voisine de l'orange dans la lumière transmise, entre le dispositif d'affichage à cristaux liquides (1) et l'unité de rétroéclairage (2).
(JA) 白色LEDランプを光源として用いる液晶表示装置において、液晶の応答速度の低下を抑制するとともに、専用のカラーフィルタを用いなくても色再現性及び赤色色度を高めるため、液晶表示パネル1とバックライトユニット2との間に透過する光の橙色付近の波長成分を吸収するバンドカットフィルタ5を備えた構成とした。
