Transflective liquid crystal display

Transflective liquid crystal display (LCD) comprising one or more pixels that are divided into a reflective and a transmissive subpixel and comprise

• an LC layer sandwiched between a front and a back electrode, being switchable between different orientations upon application of an electric field and having a twist angle φ when no field is applied,
• a front and a back polariser sandwiching the LC layer and having front and back polarisation directions,
• at least one quarter wave retardation film (QWF) between the front polariser and the LC layer, which has an optical axis parallel to its film plane, comprises a pattern of regions with quarter wave (λ/4) retardation and regions with substantially no retardation, and is arranged such that the λ/4-regions do essentially cover only the reflective subpixels,
• characterized in that
• the optical axis of the QWF is oriented at an angle of approximately 45° to the front and back polariser direction,
• the director of the LC layer at the surface facing the front electrode is oriented at an angle θ1 of from 5 to 45° relative to the polarisation direction of the front polariser, and
• the director of the LC layer at the surface facing the back electrode is oriented at an angle θ2 of from 5 to 45° relative to the polarisation direction of the back polariser.
