Abstract:
A liquid crystal display unit has wider viewing angles and a brighter display. In this display unit, an alignment film is not required to be processed for alignment of a liquid crystal, thereby simplifying the manufacturing process. A first substrate and a second substrate are disposed such that they face each other. A liquid crystal having a negative anisotropy of dielectric constant is provided between the substrates. A common electrode and an alignment film which has a pretilt angle of 90°±1° and which is not rubbed are sequentially disposed on the surface of the first substrate facing the second substrate. A plurality of pixel electrodes are provided on the surface of the second substrate facing the first substrate so as to cover a display area of the liquid crystal. A conductive light-shielding member is disposed on the second substrate and positioned around each of the pixel electrodes in a non-display area of the liquid crystal. The conductive light-shielding member is electrically insulated from the pixel electrode. An alignment film which has a pretilt angle of 90°±1° and which is not rubbed is formed on the pixel electrodes and on the light-shielding members. The conductive light-shielding member is set at substantially the same potential as the common electrode.
