  • Patent number: 8867009
    Abstract: An LCD device provides enhanced display quality. An insulating layer is formed on a first substrate. The insulating layer covers the contact portion of a switching device in which the switching device is electrically connected to a transparent electrode and has an opening for exposing a portion of the transparent electrode. A reflection electrode is electrically connected to the transparent electrode through the opening. The insulation layer covers a first portion of a driving circuit formed on the first substrate. A sealant is interposed between the first and second substrate to engage the first and second substrate and to cover a second portion of the driving circuit. Therefore, the driver circuit may operate normally, and the distortion of the signal outputted from the driver circuit may be prevented.

  • Patent number: 8867012
    Abstract: In a liquid crystal device, a shoulder portion configured to increase the distance between a element-substrate-side substrate body and a opposed-substrate-side substrate body is provided on the opposed-substrate-side substrate body in an area overlapped with a sealing material including a gap material. Therefore, in an area inside the sealing material, the gap between the element substrate and the opposed substrate is smaller than the gap therebetween in the area overlapped with the sealing material. Therefore, the layer thickness of the liquid crystal layer can be reduced without reducing the size of the gap material.

    Abstract: It is possible to separate each liquid crystal display panel from a mother board in which multiple liquid crystal display panels are formed even with a thin glass substrate, by forming a columnar spacer in the boundary between liquid crystal display panels, forming a scribe line corresponding to the columnar spacer on both sides of the counter substrate and the TFT substrate in the mother board, and forming a separation line between the scribe lines by applying a bending stress to the mother board. Since the columnar spacer is formed in a portion corresponding to the scribe line, the strength in this portion increases, so that the proper scribe lines and break lines can be formed when the thickness of the glass substrate is reduced to about 0.15 mm.
