• Subjects: DEVICES OR ARRANGEMENTS, THE OPTICAL OPERATION OF WHICH ISMODIFIED BY CHANGING THE OPTICAL PROPERTIES OF THE MEDIUM OF THEDEVICES OR ARRANGEMENTS FOR THE CONTROL OF THE INTENSITY,COLOUR, PHASE, POLARISATION OR DIRECTION OF LIGHT, e.g.SWITCHING, GATING, MODULATING OR DEMODULATING; FREQUENCY-CHANGING; NON-LINEAR OPTICS; OPTICAL ANALOGUE/DIGITAL CONVERTERS; OPTICAL LOGIC ELEMENTS; OPTICS; PHYSICS; TECHNIQUES OR PROCEDURES FOR THE OPERATION THEREOF

PROBLEM TO BE SOLVED: To obtain a liquid crystal display wherein display defects are not caused. SOLUTION: The liquid crystal display is provided with an alignment film ORI1 on the surface on a liquid crystal side of at least one substrate SUB2 of respective substrates facing each other across the liquid crystal and an insulating film INS under the alignment layer and an ion adsorbing film IAF is made to intervene between the alignment film and the insulating film. Even when an ionic decomposition product is formed from the liquid crystal and the alignment film by light irradiation, the ionic decomposition product is adsorbed by the ion adsorbing film and reduction of the voltage holding ratio of the liquid crystal can be avoided.
