Abstract

L'invention concerne un affichage à cristal liquide qui comporte une plaque avant, une plaque arrière scellée à la plaque avant pour former une enveloppe, un cristal liquide, une première électrode sur l'une des plaques, au moins une position d'un caractère ayant plusieurs segments sur l'autre des plaques, des électrodes terminales le long d'un bord de l'autre plaque, et un moyen sur l'autre plaque pour connecter électriquement les segments et les électrodes terminales. Selon l'invention, le moyen de connexion 66 est invisible à l'oeil humain et le périmètre de la première électrode peut être placé en tout emplacement le long du moyen de connexion entre les segments 62 et les électrodes terminales 67 quand les plaques sont alignées et scellées, l'activation de la première électrode avec l'un des segments ne provoquant pas un affichage visible d'une partie du moyen de connexion en alignement avec la première électrode. L'invention s'applique notamment à l'affichage numérique.Disclosed is a liquid crystal display which has a faceplate, a backplate sealed to the faceplate to form an envelope, a liquid crystal, a first electrode on one of the plates, at least one position of a character. having a plurality of segments on the other of the plates, terminal electrodes along one edge of the other plate, and means on the other plate for electrically connecting the segments and the terminal electrodes. According to the invention, the connection means 66 is invisible to the human eye and the perimeter of the first electrode can be placed at any location along the connection means between the segments 62 and the terminal electrodes 67 when the plates are aligned. and sealed, activating the first electrode with one of the segments not causing a visible display of a portion of the connection means in alignment with the first electrode. The invention applies in particular to digital display.
