REFLECTION LIQUID CRYSTAL DISPLAY AND REFLECTION LIQUID CRYSTAL DISPLAY PROVIDED WITH BUILT-IN TOUCH PANEL AND COMPRISING THE SAME

摘要

A reflection color liquid crystal display which displays an easy-to-view multi-color image with a high contrast ratio, and a liquid crystal display having a built-in touch panel of which the displayed image is not marred even when a pressure-sensitive input unit. Specifically, a reflection liquid crystal display comprising an optically reflective plate (5), a substrate (4), a liquid crystal layer (1) having a nematic liquid crystal having positive dielectric anisotropy and sandwiched between the substrate (4) and the plate (5), a first optical phase difference compensating plate (8), a second optical phase difference compensating plate (9), and a polarizing plate (10), wherein optimization is effected regarding (i) retardation of the optical phase difference compensating plates (8, 9) in the direction normal to the substrate, (ii) the angle made by the transmission axis or absorption axis of the polarizing plate (10) and the lag axis of the optical phase difference compensating plates (8, 9), (iii) the twist angle of the liquid crystal layer (1), (iv) the product of the double refractive index difference of liquid crystal of the liquid crystal layer (1) and the thickness of the liquid crystal layer, and (v) the angle made by the direction of alignment of liquid crystal molecules near the substrate (4) and the transmission axis or absorption axis of the polarizing plate (10).
