LIQUID CRYSTAL DISPLAY DEVICE AND METHOD FOR MANUFACTURING THE SAME

摘要

A liquid crystal display device with few drop marks left during manufacture is provided without degrading the image-sticking characteristics of the liquid crystal display device or other characteristics fundamental to liquid crystal display devices, such as dielectric anisotropy, viscosity, upper nematic phase temperature limit, and rotational viscosity (γ1), and a method for manufacturing such a liquid crystal display device is also provided. A liquid crystal display device 10 according to the present invention includes a first substrate 11, a second substrate 12, a liquid crystal composition layer 13 disposed therebetween, and vertical alignment layers 16 and 17 containing a polymer of a monofunctional reactive-group-containing polymerizable compound and a polyfunctional reactive-group-containing polymerizable compound.

主权项

1. A liquid crystal display device comprising a first substrate having a common electrode, a second substrate having a pixel electrode, and a liquid crystal composition layer disposed between the first and second substrates, wherein a charge is applied across the common electrode and the pixel electrode substantially perpendicularly to the first and second substrates to control liquid crystal molecules in the liquid crystal composition layer,
at least one of the first and second substrates having a vertical alignment layer that controls the orientation of the liquid crystal molecules in the liquid crystal composition layer substantially perpendicularly to surfaces of the first and second substrates adjacent to the liquid crystal composition layer, the vertical alignment layer comprising a polymer of a monofunctional reactive-group-containing polymerizable compound and a polyfunctional reactive-group-containing polymerizable compound.
