  • Patent number: 8149365
    Abstract: A liquid crystal display apparatus includes a lower substrate, an upper substrate and a liquid crystal layer interposed between the lower substrate and the upper substrate. The lower substrate includes a display part for displaying image and a driving part for providing the display part with a driving signal. The upper substrate includes a common electrode and an insulating member that electrically insulates the common electrode from the driving part. The insulating member has a lower dielectric constant than the liquid crystal layer. Thus, a parasitic capacitance between the driving part and the common electrode is reduced to prevent malfunction of the driving part, and a display quality is enhanced.

  • Patent number: 8111359
    Abstract: An array substrate includes a transparent substrate, an organic insulation layer, a pixel electrode, a reflective layer, a light blocking pattern and a switching part. The transparent substrate includes a reflective window that reflects an ambient light and a transmissive window that transmits an artificial light. The organic insulation layer disposed over the transparent substrate becomes thinner gradually at a boundary between the transmissive window and the reflective window. The pixel electrode is formed in the transmissive region. The reflective layer is disposed over the organic insulation layer of the reflective window. The light blocking pattern is disposed at the boundary between the transmissive and reflective windows to prevent a light leakage. The switching part is electrically connected to the pixel electrode to apply an image signal to the pixel electrode. Therefore, a light leakage occurring at boundary is prevented by the light blocking pattern.

  • Patent number: 7916246
    Abstract: A color filtering member for improving the brightness of a display device is presented. The color filtering member includes colored regions (e.g., regions with RBG color filters) and black-and-white regions for transmitting white light. The black-and-white regions may be colorless gaps between adjacent colored regions. Multiple planarizing layers may be deposited on the colored regions and the black-and-white regions to form a surface that is sufficiently even. The color filtering member may include an intercepting region that extends between neighboring colored regions. The position of the intercepting region is not centered between the two colored regions that it separates. Rather, the intercepting region is shifted in the direction of rubbing (in the direction of liquid crystal alignment) to more effectively cover the regions where light leakage occurs. This color filtering member may be combined with an array member and a liquid crystal layer to form a display device.
