  • Patent number: 10718983
    Abstract: To form a sufficiently large storage capacitor, a liquid crystal display device includes a liquid crystal display panel having a first substrate, a second substrate, and a liquid crystal held between the first substrate and the second substrate, the liquid crystal display panel having multiple pixels arranged in matrix. The first substrate has, in a transmissive display area provided in each of the pixels, a laminated structure containing a first transparent electrode, a first insulating film, a second transparent electrode, a second insulating film, and a third transparent electrode which are laminated in this order. The first transparent electrode and the second transparent electrode are electrically insulated from each other and together form a first storage capacitor through the first insulating film, and the second transparent electrode and the third transparent electrode are electrically insulated from each other and together form a second storage capacitor through the second insulating film.

  • Publication number: 20200225518
    Abstract: A column for defining the interval between a TFT substrate and an opposed substrate is formed at a crossing point between a drain line and a scanning line. At the crossing point where the column is formed, the drain line is formed to have a wider width to prevent light leakage. Further, at the crossing point where the column is formed, the scanning line is formed to have a narrower width to prevent increase of capacitance between the drain line and the scanning line. The column is formed at a crossing point corresponding to a specific color, e.g., a blue pixel B, so that a difference in transmittance and in characteristic of thin film transistors due to formation of the column is initially compensated.
