Abstract: A liquid crystal display and a display device, when the liquid crystal display is powered on, a pixel electrode and a common electrode form an electric field, and liquid crystal molecules are deflected under the action of the electric field. However, due to network of the polymer, the liquid crystal polymer is in a scattering state which destroys the condition of total reflection of light from a backlight between two substrates, in such a manner that at least part of light from the backlight is scattered by the liquid crystal polymer and then is emitted from one side of a first substrate. When the liquid crystal display is in an off-state, a long-axis direction of the liquid crystal molecules in the liquid crystal polymer is the same as an extending direction of a long-chain in the liquid crystal polymer, and the liquid crystal polymer is in a transparent state.
