  • Patent number: 9448432
    Abstract: It is an object to provide a display having high visibility and a transflective type liquid crystal display device having a reflection electrode having a concavo-convex structure formed without especially increasing the process. During manufacturing a transflective liquid crystal display device, a reflection electrode of a plurality of irregularly arranged island-like patterns and a transparent electrode of a transparent conductive film are layered in forming an electrode having transparent and reflection electrodes thereby having a concavo-convex form to enhance the scattering ability of light and hence the visibility of display. Furthermore, because the plurality of irregularly arranged island-like patterns can be formed simultaneous with an interconnection, a concavo-convex structure can be formed during the manufacturing process without especially increasing the patterning process only for forming a concavo-convex structure. It is accordingly possible to greatly reduce cost and improve productivity.
