ABSTRACT:
The present invention relates to a liquid crystal display panel with improved image contrast comprising an array of pixel regions and a sequence of a recycling backlight structure comprising broadband rear interference polar (RI-Polar) having a transmission axis AB with preset orientation, a spatial intensity modulation structure comprising a broadband front interference polar (FI-Polar) having a transmission axis approximately parallel to the transmission axis AB, a spectral filtering structure, and antireflection means. Each said pixel region spatially encompasses a plurality of subpixel regions. The RI-Polar and FI-Polar are multilayer structures of stacked layers. At least one layer of each structure is optically anisotropic, made by means of Cascade Crystallization Process and characterized by a globally ordered biaxial crystalline structure with an intermolecular spacing of 3.4±0.3 Å in the direction approximately parallel to the transmission axis AB. Said layer is transparent in the wavelength band of visible light, and is formed by rodlike supramolecules, which represent at least one polycyclic organic compound with a conjugated π-system and ionogenic groups.
