Patent ID: 6839113

Claim:
A liquid crystal display device comprising a first transparent substrate and a second transparent substrate arranged to confront each other, and a liquid crystal component layer sealed between said first transparent substrate and said second transparent substrate, said first transparent substrate being provided with a transparent insulating substrate, a plurality of scan lines, a plurality of signal lines provided perpendicularly to each of said scan lines, a plurality of pixels arranged in matrix form surrounded by said scan lines and said signal lines, a plurality of common electrodes provided substantially parallel at both sides of said signal lines, pixel electrodes provided between common electrodes at each of said pixels, switching elements connected to said signal lines that individually control electric fields applied to said pixel electrodes of said pixels, common lines that supply a prescribed electric potential to said common electrodes, a first alignment layer formed on the highest layer of said first transparent substrate, a second alignment layer formed on the highest layer of said second transparent substrate, said signal lines including adjacent regions, said signal lines and said adjacent regions defining signal line regions, and said pixels including apertures, said apertures and a part of said pixel electrodes defining pixel aperture regions, alignment direction of said first alignment layer at said signal line regions differing from alignment direction of said first alignment layer at said pixel aperture regions, and alignment direction of said second alignment layer at said signal line regions differing from alignment direction of said second alignment layer at said pixel aperture regions.
