The Anti-Shock Characteristic of the Panels which Consist of Two Adhering Glass Plates with Rib for (A)FLCD

Abstract

It is expected that the panels which consist of two adhering glass plates with rib have better anti-shock and anti-press characteristics than those comprised of two glass substrates in which silica beads dispersed as spacer. In this forum, we will present about anti-shock and anti-press characteristics of some of those panels which we developed. The ribs of these studied panels consist of positive photoresist which is commercially available, and the panels are filled in with (A)FLC, such as SCE9(Hoechst), CS1013, CS1014, CS1027 and CS4000(Chisso Corp.). All the panels are treated with temperaturegradient-cooling method that we had developed to be uniform phase(SmC^* or SmC_A^*) and orientation of (A)FLC in those. In order to compare the anti-press characteristic of the panels, the minimum antipressure (Pmin) causing zigzag or line-like defects and the maximum anti-pressure (Pmax) at which defects would disappear completely within 1 minute following termination of press are measured with push-pull scale. In result, it is found to maintain the uniformity of the phae and the orientation of (A)FLC such as CS1014, CS1027 and CS4000 in the panels, even if the pressure of 100 Ncm^-2 applied on those.
