The invention relates to a transflective liquid crystal display (LCD) with a polymerised LC film comprising at least one photoisomerisable compound and having a pattern of regions with different retardation and/or different orientation of the LC material.

Transflective LCD comprising a patterned retardation film

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

Transflective vertically aligned liquid crystal display with in-cell patterned quarter-wave retarder
