Abstract
The utility model discloses a two -sided display and display device, including two the liquid crystal display panel, when the liquid crystal display panel switched on, the pixel electrode and NULL formed the electric field, and the liquid crystal molecules takes place to deflect under the electric field action, still because the polymer network effect makes liquid crystal polymer be the total reflection condition of light between two base plates that the backlight had been destroyed to the scattering attitude, so had at least partial light to jet out on one side of first base plate after the liquid crystal polymer scattering in the backlight. When the liquid crystal display panel is in the OFF state, the extending direction unanimity of long -chain among the liquid crystal molecules's major axis direction and the liquid crystal polymer among the liquid crystal polymer, liquid crystal polymer is transparent attitude. Therefore above -mentioned the liquid crystal display panel, through electric field ON state and OFF state effect, the liquid crystal molecules can take place rotatoryly or resume to reach liquid crystal display's effect. But owing to compare the setting of having saved two polaroids with current the liquid crystal display panel, consequently has higher transparency when being applied to two -sided display.
