Abstract

PURPOSE: To obtain the display element which is good in the evenness of orientation and durability and high in spectral transmissivity despite glass frit sealing by using the specific polyimide-base co-condensation polymer for the orientation films of liquid crystals.
CONSTITUTION: Not the compound in which benzene rings are directly connected to themselves by the diamine having three or more pieces of ester, sulfone, carbonyl, methylene groups in the diamine chain is used as shown in formula to enhance flexibility and spectral transmissivity without decreasing heat resistance. As a result of this, the element as the superior heat resistance and durability which do not degrade even if glass frit sealing is done at 430W450°C, and these yield the display device having the superior orientation films which are less in coloring, high in spectral transmissivity and are stable even if relative humidity is high.
