Abstract: This invention relates to a transflective liquid crystal display device, comprising an upper first substrate (2), a lower second substrate (3), comprising means for defining reflective (12) and transmissive parts (13) of the display. A liquid crystal layer (4) is arranged between the first substrate (2) and the second substrate (3). For the reflective parts (12), a reflective layer (5) is provided to reflect ambient light falling into the display device. The transflective LCD device further comprises an in-cell retardation layer (7) at least for the reflective parts (12), being arranged between said reflective layer (5) and the liquid crystal layer (4). Preferably the in-cell retardation layer (7) also extends over the transmissive parts (13).
