COLOUR LIQUID CRYSTAL DISPLAY AND PATTERNED COMPENSATION PANEL

摘要

The present invention relates to a colour liquid crystal display (LCD) device and, more particularly, to the improvement of colour LCDs aimed to achieving a high contrast ratio and better colour rendering at wide viewing angles. The disclosed colour liquid crystal display comprises first and second polarizing plates (501,503) facing each other, a liquid crystal cell situated between said first and second polarizing plates, and at least one compensation panel situated between said first and second polarizing plates. The compensation panel (509) comprises at least one matrix of patterned birefringent elements (510) of / kinds having different retardation, wherein / is 3, 4 or 5. The patterned birefringent elements comprise at least one retardation layer comprising at least one polycyclic organic compound with a conjugated p -system and functional groups which are capable of forming non-covalent bonds.
