Abstract
A liquid crystal cell, a manufacturing method thereof and a use thereof are provided in the present disclosure. The liquid crystal cell is in a normally transparent mode, and has excellent transmittance-variable characteristics in a transparent mode and a scattering mode and excellent haze characteristics in the scattering mode. Such liquid crystal cell may be applied to various light modulation devices, such as a smart window, a window protective film, a flexible display element, a light shielding plate for transparent displays, an active retarder for 3D image displays or a viewing angle control film.
Claims14
A liquid crystal cell comprising:
- two substrates disposed opposite to each other;
- and
- a liquid crystal layer present between the two substrates and having an average current density of 30 μA/cm2 to 60 μA/cm2, wherein the average current density is an average value of current densities measured by applying an alternating-current voltage at a first voltage of 40 V and a frequency of 60 Hz to the liquid crystal cell from 0 ms to 8 ms after a fifth cycle.
A method for manufacturing a liquid crystal cell comprising two substrates disposed opposite to each other and a liquid crystal layer present between the two substrates, wherein the method comprises:
- adjusting the liquid crystal layer to have the average current density of 30 μA/cm2 to 60 μA/cm2, wherein the average current density is an average value of current densities measured by applying an alternating-current voltage at a voltage of 40 V and a frequency of 60 Hz to the liquid crystal cell from 0 ms to 8 ms after a fifth cycle.
