Abstract:
(EN) A direct view type liquid crystal display panel with micro-lens array is provided for making it possible to carry out high degrees of a viewing angle characteristic, a contrast and a brightness display. The liquid crystal display panel with micro-lens array is comprised of a liquid crystal panel with a plurality of pixels, a micro-lens array provided on a light incident side of the liquid crystal panel, a first polarizer and a first optical compensating device that are provided on a light projecting side of the liquid crystal panel, and a second polarizer and a second optical compensating device that are provided on a light incident side of the micro-lens array, wherein retardation in a thickness direction of the first optical compensating device is longer than retardation in a thickness direction of the second optical compensating device.
(FR) Panneau d'affichage à cristaux liquides et à réseau de microlentilles du type à vision directe, permettant d'obtenir un haut degré de caractéristique d'angle de vue, de contraste et de luminosité. Le panneau d'affichage à cristaux liquides et à réseau de microlentilles se compose d'un panneau à cristaux liquides ayant une pluralité de pixels, d'un réseau de microlentilles prévu sur un côté d'incidence de lumière du panneau à cristaux liquides, d'un premier polariseur et d'un premier dispositif de compensation optique prévus sur un côté de projection de lumière du panneau à cristaux liquides, et d'un second polariseur et d'un second dispositif de compensation optique prévus sur un côté d'incidence de lumière du réseau de microlentilles, le retard optique dans le sens de l'épaisseur du premier dispositif de compensation optique étant supérieur au retard optique dans le sens de l'épaisseur du second dispositif de compensation optique.
(JA)  視野角特性及びコントラストが高く、高輝度の表示が可能な直視型のマイクロレンズアレイ付き液晶表示パネルを提供する。  本発明のマイクロレンズアレイ付き液晶表示パネルは、複数の画素を有する液晶パネルと、液晶パネルの光入射側に設けられたマイクロレンズアレイと、液晶パネルの光出射側に設けられた第1の偏光板及び第1の光学補償素子と、マイクロレンズアレイの光入射側に設けられた第2の偏光板及び第2の光学補償素子とを備え、第1の光学補償素子の厚さ方向のリタデーションが、第2の光学補償素子の厚さ方向のリタデーションよりも大きい。
