Analysis of Display Failure around the Injection Corner of LCD Cell

Abstract

Various kinds of display failure are known around the injection corner of Liquid Crystal Display (LCD) cell. Chromatogram phenomenon ( effect ) is a well known display failure observed after the injection process of liquid crystal. It is said that impurities contained in liquid crystal are absorbed on the alignment film around the injection corner in a form of chromatogram pattern. This kind of failure has been examined microanalytical technique like FT-IR-Microscopy and Microsampling MS.
