Abstract
An active matrix liquid crystal display device having first and second substrates, a liquid crystal layer disposed between the first and second substrates, plural image signal lines and scan signal lines being formed on the substrate and each pixel region being formed by adjacent image signal lines and adjacent scan signal lines having at least an active device. At least a pixel electrode is connected to the active device and at least a counter electrode in each pixel, and the pixel electrode and the counter electrode are provided on the first substrate. A first alignment film is formed over the pixel electrode and counter electrode on the first substrate at least in a pixel forming region, and a second alignment film is formed on the second substrate at least in the pixel forming region. Rubbing directions of the first and second alignment films are substantially parallel to each other.
