Abstract
(EN)
A manufacturing device for a three-dimensional liquid crystal display device according to the present invention forms a right-eye alignment region and a left-eye alignment region on an alignment film by irradiating the alignment film with exposure light while aligning the position of photomasks (3a, 3b) with the pixel line in a liquid crystal display panel (1) with reference to an alignment mark (9) on the liquid crystal display panel (1) having the alignment film applied or bonded thereto, and further forms a liquid crystal film, thereby forming directly on the liquid crystal display panel (1) a right-eye polarization section and a left-eye polarization section that are composed of a retardation layer. In the present invention, the need to bond the liquid crystal display panel (1) and a retardation plate together is eliminated, and polarization sections of the retardation layer can accurately overlap the respectively corresponding right-eye pixels and the left-eye pixels in the liquid crystal display panel (1). Therefore, quality degradation of a stereoscopic image due to bonding accuracy can be prevented.

Selon la présente invention, un dispositif de fabrication pour un dispositif d'affichage à cristaux liquides en trois dimensions forme une région d'alignement d'œil droit et une région d'alignement d'œil gauche sur un film d'alignement, en irradiant le film d'alignement avec une lumière d'exposition, tout en alignant la position de photo-masques (3a, 3b) avec la ligne de pixels dans un panneau (1) d'affichage à cristaux liquides, avec référence à un repère (9) d'alignement sur le panneau (1) d'affichage à cristaux liquides, ce-dernier ayant le film d'alignement appliqué ou lié à celui-ci ; ce dispositif de fabrication forme en outre un film à cristaux liquides, ce qui permet de former directement sur le panneau (1) d'affichage à cristaux liquides une section de polarisation d'œil droit et une section de polarisation d'œil gauche, qui sont composées d'une couche de retard. Dans la présente invention, le besoin de lier le panneau (1) d'affichage à cristaux liquides et une plaque de retard est éliminé, et des sections de polarisation de la couche de retard peuvent chevaucher avec précision respectivement les pixels d'œil droit et les pixels d'œil gauche correspondants dans le panneau (1) d'affichage à cristaux liquides. par conséquent, la dégradation de qualité d'une image stéréoscopique en raison de la précision d'assemblage peut être évitée.

 本発明に係る3次元液晶表示装置の製造装置は、配向膜が塗布又は貼り付けられた液晶表示パネル(1)のアライメントマーク(9)を基準にして、フォトマスク(3a,3b)の位置を液晶表示パネル(1)の画素ラインに整合させながら露光光を照射することにより、右目用配向領域と左目用配向領域とを配向膜に形成し、更に液晶膜を形成し、液晶表示パネル(1)上に直接位相差層からなる右目用偏光部と左目用偏光部とを形成する。 本発明においては、液晶表示パネル(1)と位相差板とを貼り合わせる必要がなく、液晶表示パネル(1)の右目用画素および左目用画素にそれぞれ対応する位相差層の偏光部を精度よく重ねることができる。従って、貼り合わせ精度に起因する立体画像の品質低下を防止できる。
