Abstract
A liquid crystal device has a structure in which an electric field is applied across a liquid crystal in a direction substantially parallel to the plane of a substrate. A conductive film is formed on a first substrate on which an electric field control is provided, and also on a color filter substrate located opposite the first substrate, and the conductive films are maintained at either a ground voltage, a common electrode voltage, the center voltage of an image signal, a non-selection voltage of a scanning signal, or a logic voltage of an external driver or otherwise the voltage of the conductive films is maintained in a floating state. The liquid crystal device having the above structure displays a high-quality image without encountering an influence of electrostatic charges.
Claims4
A liquid crystal device, comprising:
- a pair of substrates,
- a liquid crystal disposed between said pair of substrates, a first one of said substrates having, thereon, scanning signal lines and image signal lines disposed in a matrix form inside a pixel area, an active element connected to each of the scanning signal lines and image signal lines, a pixel electrode connected to the active element, and a common electrode, an electric field being applied across the liquid crystal in a direction substantially parallel to a plane in which said pair of substrates lie,
- a sealing element disposed around the pixel area that seals said pair of substrates, and
- a light-shielding metal film formed inside of a second one of said substrate, the light-shielding metal film extending outside the sealing area where the sealing element are formed, being electrically connected to a predetermined electrode.
