Title (EN) LCD DEVICE
(FR) DISPOSITIF A DIODES ELECTROLUMINESCENTES
Abstract:
(EN) An LCD device comprises two spaced transparent plate assemblies, each comprising a plate (1, 2), barrier layer (6), alignment layer (7), array of electrodes (4, 5), and spacers (10, 12) for maintaining a space between the plate assemblies for a liquid crystal material (3). The spacers (10) comprises spaced elongate strips extending across the plate assemblies; and elongate adhesive strips (12) for bonding the assemblies together. The adhesive strips extend across the plate assemblies parallel to the spacers and defining together with the spacers parallel channels for the liquid crystal material (3). One of the plates is provided with a colour filter (2a) comprising elongate regions of coloured pixels (2b) and elongate non-pixel regions (2c), and the strips of said spacer means and said adhesive are located at the non-pixel regions. The regions of coloured pixels are arranged in a repeating pattern of parallel lines of red, green and blue pixels, and the strips of said spacers and said adhesive are located between each line of coloured pixels.
(FR) L'invention concerne un dispositif à diodes électroluminescentes, constitué de deux ensembles plaques transparents disposés à distance l'un de l'autre, chaque ensemble comprenant une plaque (1, 2), une couche de protection (6), une couche d'alignement (7) et un réseau d'électrodes (4, 5); et d'écarteurs (10, 12), qui maintiennent entre les ensembles plaques un espace destiné à un matériau à cristaux liquides (3). Les écarteurs (10) comprennent des bandes allongées disposées à distance les unes des autres, qui traversent les ensembles plaques, et des bandes adhésives (12), qui relient les ensembles entre eux. Les bandes adhésives traversent les ensembles plaques parallèlement aux écarteurs et définissent avec ces derniers des canaux parallèles destinés au matériau à cristaux liquides (3). L'une des plaques comporte un filtre couleur (2a) comprenant des zones allongées constituées de pixels colorés (2b) et des zones allongées sans pixels (2c), les bandes desdits écarteurs et dudit adhésif étant situées au niveau des zones sans pixels. Les zones de pixels colorés sont disposées selon un motif répété de lignes parallèles constituées de pixels rouges, verts et bleus, et les bandes desdits écarteurs et dudit adhésif sont disposées entre les lignes de pixels colorés.
