| description | This object aims to provide a glass substrate for a display device, a liquid crystal display panel and a liquid crystal display device that are configured to get rid of uneven display on a display panel in which cell assembly is completed and to require no post process or to simplify a post process. A liquid crystal panel (30) is provided with glasses (10, 32) arranged opposite to each other, a liquid crystal layer (34) that is inserted between the two glasses (10, 32), and ball-like spacers (33a, 33b) that are arranged in contact with the opposite surfaces of the two glasses (10, 32). Under such measurement conditions that the glass (10) is11 mm in thickness and a cutoff value is in the range of 0.8-8mm, an amplitude (A) is equal to or less than 2µm when a period (D) between spatial frequencies in the range of 2-500/mm in accordance with a spectral analysis of a filtered waviness curve is equal to or more than 20 mm and the amplitude (A) is equal to or more than 18 nm when a period (D) is equal to or less than 20 mm.
L'invention vise à procurer un substrat en verre pour un dispositif d'affichage, un panneau d'affichage à cristaux liquides et un dispositif d'affichage à cristaux liquides qui sont configurés pour se débarrasser d'un affichage irrégulier sur un panneau d'affichage dans lequel un assemblage de cellules est achevé, pour ne pas nécessiter un quelconque post-traitement ou pour simplifier un post-traitement. A cet effet, l'invention porte sur un panneau à cristaux liquides (30) qui est pourvu de verres (10, 32) agencés opposés l'un à l'autre, une couche de cristaux liquides (34) qui est introduite entre les deux verres (10, 32), et des entretoises de type bille (33a, 33b) qui sont agencées en contact avec les surfaces opposées des deux verres (10, 32). Dans des conditions de mesures telles que le verre (10) présente une épaisseur de 11 mm et une valeur de coupure se situant dans la plage de 0,8-8 mm, une amplitude (A) est égale ou inférieure à 2 µm lorsqu'une période (D) entre des fréquences spatiales dans la plage de 2-500/mm selon une analyse spectrale d'une courbe d'ondulation filtrée est égale ou supérieure à 20 mm, et l'amplitude (A) est égale ou supérieure à 18 nm lorsqu'une période (D) est égale ou inférieure à 20 mm. |
