Provided are a liquid crystal panel capable of achieving a small light-shielding angle in a narrow viewing angle mode and a display device including the liquid crystal panel. The liquid crystal panel sequentially includes: a first polarizing plate with a first absorption axis; a first substrate including a first electrode; a liquid crystal layer containing liquid crystal molecules; and a second substrate including a second electrode, wherein in a plan view, a director of the liquid crystal molecules with no voltage applied and the first absorption axis form an angle α of not smaller than 5° and not greater than 20° or not smaller than 65° and not greater than 80°.

A privacy display comprises a spatial light modulator and a compensated switchable liquid crystal retarder arranged between first and second polarisers arranged in series with the spatial light modulator. In a privacy mode of operation, on-axis light from the spatial light modulator is directed without loss, whereas off-axis light has reduced luminance. The visibility of the display to off-axis snoopers is reduced by means of luminance reduction over a wide polar field. In a wide angle mode of operation, the switchable liquid crystal retardance is adjusted so that off-axis luminance is substantially unmodified.

A polarizing film including a polarizer that is a cured product of a polymerizable liquid crystal composition is provided. The polymerizable liquid crystal composition contains both a polymerizable liquid crystal compound having at least one polymerizable group and a dichroic coloring matter. The polarizer is laminated on a surface, having a pore size of 0.45 nm to 0.57 nm, of a base material. The pore size is obtained by converting, into a diameter, an average free volume radius calculated by a positron lifetime measurement method in which the positron lifetime is measured by irradiating the surface with positrons with an injection energy of 3 kV.
