A liquid crystal display device and a method of manufacturing the same. The liquid crystal display device includes a plurality of pixel cells on a substrate and a common voltage line. The common voltage line provides a common voltage to the pixel cells, and includes first to third s interconnection patterns which are sequentially stacked over the substrate. Each of the pixel cells includes a storage capacitor which includes a lower electrode, and an upper electrode over the lower electrode. The second interconnection pattern includes the same material as a material of the upper electrode, and is formed in the same process as a process of the upper electrode.

A bistable liquid crystal display based on the bend and splay configurations has been demonstrated. This display can be switched between the bend and splay deformation in a three-electrode configuration and has infinite bistable lifetime. It also has wide viewing angles, excellent contrast ratios, and very fast selection. Selection electric pulse duration of 50μs can be used to switch this display, implying the possibility of a high information content applications.

A new electrically addressed and thermally erased cholesteric cell has been investigated. The helical pitch of the cholesteric mixture becomes longer with increasing temperature. After an electric field is applied to the mixture, a focal conic texture is formed. When being heated, the cholesteric phase has a tendency to adopt a planar texture. This is because the planar texture is stabler than the focal conic one when the pitch is longer. Both textures are stable at room temperature without external fields.

A photo-alignment layer having excellent long-term stability to light and heat is manufactured by coating a material for the photo-alignment layer, which contains a dichroic dye having two or more polymerizable groups per molecule, on a substrate, and exposing the coating layer to polarized light, thereby imparting a photo-alignment function, and polymerizing the polymerizable groups by heating or light exposure.

Method of manufacturing photo-alignment layer

By introducing benzoyl–benzene into a cholesteric liquid crystal, the helix unwinding voltage was reduced. This reduction was roughly proportional to the concentration of the dopant and was present for driving frequencies across the audio spectrum. It is believed that this voltage reduction is primarily due to a perturbation of the intermolecular coupling in the liquid crystal mixture. It was found that so long as the long-range order was not destroyed, the helix unwinding voltage could be reduced by as much as 24% at 60 Hz.

Helix unwinding of doped cholesteric liquid crystals

This invention provides a method and apparatus for driving bistable cholesteric liquid crystal displays. The method and apparatus provided a display in which all the pixels are initially driven to the P state. Selected pixels for the display are then driven to the FC state to provide the desired message. The state of the pixels is then maintained for a viewing period prior to any resetting of the display to the P state. The switching from the P state to the FC state allows fast addressing times and lower voltages to be used in driving the display.

Method and apparatus for driving reflective bistable cholestric displays

The invention provides a method for controlling the grey-scale modulation of a reflective bistable cholesteric display by applying selected sequences of high and low pulses to modulate the cholesteric domain size and helical axis orientation. Non-mesogenic dopants may also be added to reduce the drive voltage.

Method, materials and apparatus for driving gray-scale bistabel cholesteric displays

In the study of the transition dynamics, we found that the reflectance of bistable cholesteric displays depended on the addressing sequence of the bipolar pulses. Two different pulse amplitudes corresponding to the high and low voltages about the quiescent point were chosen. By a proper permutation of such pulses, the final reflectance of even difference could be obtained for gray-scale display applications. In contrast with the root-mean-square (rms) modulation techniques, this scheme proposed for the first time does not primarily depend on the rms voltage. In this paper, we study the electro-optics and the domain characteristics, and propose a phenomenological proposition to describe this effect. We shall also extend our previous driving scheme to demonstrate the gray-scale control at 5 ms/line addressing.
