Reflective liquid crystal display device including organic film prevented from being degraded due to moisture absorption
View Patent ↗A reflective liquid crystal display device having high reliability and excellent display is provided by preventing degradation and peeling of an organic film provided in order to impart an uneven shape to a reflective metal film. The reflective liquid crystal display has a configuration in which a liquid crystal layer is held in the space formed by a pair of substrates arranged opposing to each other and a seal member provided on the periphery portion of the substrate pair, an organic film, a reflective metal film, color filters, an overcoat film, an electrode substrate film, electrode layers, and an orientation film are laminated in order on the liquid crystal layer side of one substrate of the substrate pair, and the organic film is formed in the neighborhood region of the end of the seal member provided on the periphery portion of the aforementioned substrate.
1. A reflective liquid crystal display device, comprising:
a liquid crystal layer enclosed with a pair of substrates arranged opposing to each other and a seal member provided on a periphery portion of the pair of substrates;
at least an organic film, a reflective metal film, an overcoat film, an electrode layer, and an orientation film laminated on a liquid crystal layer side of one substrate of the pair of substrates; and
wherein the organic film has an outer periphery end portion and the outer periphery end portion of the organic film is located in an inside portion of an inner perimeter side of the seal member provided on the periphery portion of the substrates in a plan view of the substrates.
2. The reflective liquid crystal display device according to claim 1 , wherein the organic film is formed in a region 0 mm to 5 mm inside the end of the inner perimeter side of the seal member provided on the periphery portion of the substrates.
3. The reflective liquid crystal display device according to claim 1 , wherein the end of the inner perimeter side of the seal member is arranged outside an inclined portion formed on a surface of the electrode layer by the overcoat film surmounting a height difference formed between the organic film and the one substrate.
4. The reflective liquid crystal display device according to claim 1 , wherein the overcoat film is formed to cover an end of the organic film.
5. The reflective liquid crystal display device according to claim 1 , wherein color filters are directly formed on the reflective metal film.
