Abstract:
    The invention pertains to a normally white super twisted nematic, NW-STN, display comprising a super twisted nematic, STN, display cell and a compensation layer, characterized in that the compensation layer is a twisted liquid crystalline polymer and has an optical retardation OR which is 10 to 50 % of the OR of the display cell in the off-state, and wherein the absolute value of the twist angle of the compensation layer is between 150 DEG and 10 DEG and is at least 90 DEG smaller than the absolute value of the twist angle of the STN display cell. Preferably, the compensation layer of the NW-STN display is temperature matched with the STN display cell.
