Abstract
A liquid crystal display device eliminating an uneven display is presented. A D-STN type liquid crystal display device has a compensation cell and a liquid crystal cell for display wherein a difference between the average thicknesses of at least two adjacent glass substrates among glass substrates existing in the compensation cell and the liquid crystal cell for display is 4 μm or more, and preferably not more than 50 μm.
Claims18
In a D-STN type liquid crystal display device having a compensation cell and a liquid crystal cell for display, said liquid crystal display device being characterized in that a difference between the average thicknesses of at least two adjacent glass substrates among glass substrates existing in the compensation cell and the liquid crystal cell for display is 4 μm or more.
In a D-STN type liquid crystal display device having a compensation cell and a liquid crystal cell for display, said liquid crystal display device being characterized in that a glass substrate constituting adjacent glass substrates in the compensation cell and the liquid crystal cell for display does not have a tilt of thickness difference of 0.1 μm/mm or more or a tilt of thickness difference of −0.1 μm/mm or less at at least three consecutive points that are plotted arbitrarily at positions 2 mm away from each other in an arbitrary line in parallel to a long-side direction or a short-side direction of adjacent glass substrates in an overlapping state.
In a D-STN type liquid crystal display device having a compensation cell and a liquid crystal cell for display, said liquid crystal display device being characterized in that a glass substrate constituting adjacent glass substrates does not have a specified portion in which a thickness difference at same positions in the adjacent glass substrates is 0.1 μm or less.
