Liquid crystal display and display device

A liquid crystal display comprising:

• a first substrate and a second substrate disposed opposite to each other;
• a liquid crystal polymer located between the first substrate and the second substrate;
• a pixel electrode and a common electrode located between the first substrate and the second substrate and insulated from each other;
• the pixel electrode and the common electrode being located on a same side of the liquid crystal polymer;
• an auxiliary electrode positioned between the first substrate and the second substrate, and the auxiliary electrode and the pixel electrode being respectively located on both sides of the liquid crystal polymer, the auxiliary electrode being configured to increase the horizontal component of the electric field formed by the pixel electrode and the common electrode;
• and
• a side backlight configured to provide a light source,
• wherein the liquid crystal polymer is formed by irradiation of a mixture of a liquid crystal, a polymerizable liquid crystal monomer and a photoinitiator under ultraviolet light;
• when the liquid crystal display is in an off-state, a long-axis direction of liquid crystal molecules in the liquid crystal polymer coincides with an extending direction of a long-chain in the liquid crystal polymer, the liquid crystal polymer is in a transparent state without two polarizers;
• and when the liquid crystal display is powered on, the pixel electrode and the common electrode form an electric field, the liquid crystal molecules in the liquid crystal polymer are deflected under action of the electric field, however, due to network of the polymer, the liquid crystal polymer is in the scattering state, and the scattering state destroys the condition of the light from the backlight totally reflecting between the two substrates, so that at least part of light from the backlight is scattered by the liquid crystal polymer and emitted from one side of the first substrate;
• and
• when the liquid crystal in the liquid crystal polymer is a negative liquid crystal, and the liquid crystal display is in the off-state, the long-axis direction of the liquid crystal molecules in the liquid crystal polymer is perpendicular to the cell gap direction of the liquid crystal display.
