Liquid crystal display unit and method of manufacturing the same

#The present invention relates to a liquid crystal display unit that includes a liquid crystal display device in which a liquid crystal layer is sealed between a pair of substrates having an alignment film on opposed faces thereof and a method of manufacturing the liquid crystal display unit.

#In recent years, a liquid crystal display (LCD: Liquid Crystal Display) is often used as a display monitor for a liquid crystal television, a notebook personal computer, a car navigation system and the like. The liquid crystal display is categorized into various display modes (methods) according to molecular arrangement (alignment) of liquid crystal molecules contained in a liquid crystal layer sandwiched by substrates. As a display mode, TN (Twisted Nematic) mode in which twisted liquid crystal molecules are aligned in a state that a voltage is not applied is well-known. In the TN mode, the liquid crystal molecules have positive dielectric constant anisotropy, that is, characteristics that the dielectric constant in the long axis direction of the liquid crystal molecules is larger than that in the short axis direction of the liquid crystal molecules. Thus, the liquid crystal molecules are arrayed in a direction vertical to a substrate face while the alignment direction of the liquid crystal molecules is sequentially rotated in a plane in parallel with the substrate face.

#Meanwhile, attention is drawn to VA (Vertical Alignment) mode in which liquid crystal molecules are aligned vertical to a substrate face in a state that a voltage is not applied. In the VA mode, the liquid crystal molecules have negative dielectric constant anisotropy, that is, characteristics that the dielectric constant in the long axis direction of the liquid crystal molecules is smaller than that in the short axis direction of the liquid crystal molecules, and a wider view angle is able to be realized than TN mode.
