  • Patent number: 7557899
    Abstract: A liquid crystal display device includes a first substrate including a thin film transistor, a data line, a pixel electrode, and a common electrode, a second substrate, and liquid crystal sandwiched between the first and second substrates, wherein an image signal is applied to the thin film transistor through the data line to generate an electric field between the pixel electrode receiving the image signal and the common electrode such that the liquid crystal is rotated by the electric field in a plane which is in parallel with the first substrate. The first substrate includes an electrically insulating inorganic film covering the data line therewith, a first island-shaped electrically insulating organic film formed on the electrically insulating inorganic film above the data line, and a shield common electrode covering the first island-shaped electrically insulating organic film therewith and overlapping the data line when viewed vertically.

  • Patent number: 6995819
    Abstract: A semi-transmissive liquid crystal display device of the present invention is so configured that a diffraction film and a light scattering layer are provided on a color-filter substrate on the side thereof on which a display screen resides, and the light scattering layer is disposed nearer a liquid crystal layer than the diffraction film. The semi-transmissive liquid crystal display device thus configured has improved viewing-angle characteristics in the transmissive mode.
