Liquid crystal display

A liquid crystal display device comprising:

• an STN liquid crystal cell with 180° to 270° twisted nematic liquid crystals sandwiched between a pair of transparent substrates having respective transparent electrodes;
• a retardation film disposed on a visible side of the STN liquid crystal cell;
• a first polarizing film disposed on an outer side of the retardation film;
• and
• a second polarizing film, a retardation film for circularly polarized light, a cholestric liquid crystal polymer sheet, a translucent light absorbing member and a backlight disposed successively on a side of the STN liquid crystal cell, opposite from the visible side thereof.

A liquid cell display device comprising:

• a TN liquid crystal cell with about 90° twisted nematic liquid crystals sealed in-between a pair of transparent substrates having respective electrodes;
• a first polarizing film disposed on a visible side of the TN liquid crystal cell;
• and
• a second polarizing film, a retardation film for circularly polarized light, a cholestric liquid crystal polymer sheet and a backlight disposed successively on a side of the TN liquid crystal cell, opposite from the visible side thereof,
• wherein a face of said backlight, opposite to said cholestric liquid crystal polymer sheet, has a function of scattering polarized light.
