PBa22 液晶パネル内のイオン挙動

抄録

The ions behavior in the liquid crystal cell, which causes display non-uniformity, depends on panel composition, especially the insulating layer composition on the display electrode mainly. This is because the difference in conductivity in the liquid crystal cell by the insulating layer composition gives the relaxation speed of the inner polarization of ions a big influence. Especially, in the cell that has an insulating Layer on the one side of electrode, only when negative voltage is applied to the electrode without insulating layer, electric current flows. Its electric current shows exponential dependence on the square root of electric field. It suggests that "Electron Injection" occurs at LC/electrode interface by the Schottky effect.
