摘要:
A improved liquid crystal display device including two substrates each having transparent electrode thereon disposed in parallel while keeping a predetermined gap by means of pillar-shaped spacers and a liquid crystal held between said first and second substrates is proposed. In the liquid crystal display device, density or volume of the number of the pillar-shaped spacers provided in the off-display area is higher than those of a density of the number of said pillar-shaped spacers provided in the display area. This change is made continuously or stepwise along areas. The spacers are preferably disposed so that a contact area between the spacer and a rubbing cloth during the rubbing process is minimized, or so that an orientation defective area caused starting from the spacer does not extend into the pixel area, or so that a plurality of spacers are disposed along a flow of liquid crystal from filling port into the gap between the first and second substrate.
