  • Patent number: 9746722
    Abstract: A liquid crystal display comprises: an upper panel including an upper substrate on which a plurality of thin film layers are formed; a lower panel including a lower substrate on which a plurality of thin film layers are formed; a liquid crystal layer positioned between the upper panel and the lower panel; and a sealing member bonding between the upper panel and the lower panel and constraining the liquid crystal layer. The lower panel includes an aligning agent margin part which is positioned inside the sealing member on the lower substrate and dummy pixels which are positioned at the aligning agent margin part and which enclose a display area. By this configuration, it is possible for a liquid crystal display to be capable of reducing the peripheral area of the display panel so as to expand the display area or making the peripheral area seem smaller to make the display area seem larger.
