Abstract:
There is provide a low cost liquid display panel with high image quality, the liquid crystal display in which temperature compensation is unnecessary and image quality is not affected by temperature changes of the surrounding environment. In the active matrix cholesteric liquid crystal display panel, the time Tw for applying voltage to the liquid crystal layer at the time of image writing is set so that the variation ΔVs depending on temperature of the writing voltage which makes the liquid crystal layer to show approximate 50% of the maximum reflectance is less than or equal to a predetermined value within a predetermined temperature range.
