Abstract:
The invention relates to a transflective vertically aligned (VA) liquid crystal display (LCD) comprising a patterned quarter wave foil (QWF). The display (10) comprises, in a particular, front and back electrodes (14a, 14b, 14c) provided on transparent substrates (11a, 11b) and sandwiching a LC medium (12), so as to define reflective (10a) and transmissive sub-pixels (10b). The patterned QWF (16), which is preferably provided inside the LC cell (in-cell application), has regions (16a) which provide a defined retardation and cover the reflective sub-pixels (10a), and regions (16b) having no on-axis retardation and covering the transmissive sub-pixels (10a).
