Beschreibung
Zusammenfassung:	A polymerizable liquid crystal compositionof the present invention contains at least twopolymerizable compounds having different rates of polymerization reaction and a liquid crystalcompound. The polymerizable liquid crystal composition is characterized in that the rate of polymerization reaction of the polymerizable compounds contained in the composition can be easily made suitable for the specification of a UV irradiation lamp, the pretilt angle, which affects the display performance, can be easily controlled, a problem of unpolymerization of polymerizable compounds, whichaffects display unevenness, image sticking, etc., can be solved, and thus a PSA liquid crystal display element having good performance and high reliability can be produced. The polymerizable liquid crystal composition is suitable asa practical liquid crystal composition.
