Description

TECHNICAL FIELD [0001] The present invention relates to a liquid crystal composition having negative dielectric anisotropy and a display device using the same. [0002]

The present invention relates to a liquid crystal composition, and more particularly to a liquid crystal composition having suitable optical anisotropy, suitable dielectric anisotropy, relatively high transparency and good anti-UV stability, and a liquid crystal display device comprising the liquid crystal composition.

Liquid crystals mainly act as dielectrics in liquid crystal display devices because this kind of optical properties can be affected by the applied voltage. The liquid crystal display may be classified into a phase change PC, a twisted nematic TN, a super twisted nematic (STN), an electrically controlled birefringence (ECB), an optically compensated bend (OCB) , Transverse electric field switching, vertical alignment (VA) and polymer stable alignment (PSA) modes.

Currently used liquid crystal display devices are mainly TN type liquid crystal display devices. However, this has the drawback of intense contrast-time dependence. In addition, it is a VA type liquid crystal display element having a so-called wider viewing angle. The liquid crystal case of a VA type liquid crystal display element includes a liquid crystal dielectric layer between two transparent electrodes, wherein the liquid crystal medium usually has a negative dielectric anisotropy value. In the electrostatic state, the molecules of the liquid crystal layer have an orientation that is perpendicular to the electrode ground plane (vertical plane) or an orientation that is inclined to the vertical plane. When a voltage is applied to the electrode, vertical alignment occurs in which the liquid crystal molecules are parallel to the electrode surface.

In addition, the OCB type liquid crystal display device has a liquid crystal layer of so-called " bending " orientation and a usual positive dielectric anisotropy due to the birefringence effect. When a voltage is applied, a reorientation occurs in which liquid crystal molecules are perpendicular to the electrode surface. In addition, the OCB type liquid crystal display device typically includes one or a plurality of double refraction optical retardation films, and prevents unexpected optical transparency of the flexure case in a dark state. The OCB type liquid crystal display device has a wider viewing angle and shorter response time than the TN type liquid crystal display device.

In a PSA type liquid crystal display device, a liquid crystal composition and a polymerizable liquid crystal composition formed of a polymerizable compound are arranged between substrates, a voltage is applied between the substrates depending on the situation to orient liquid crystal molecules, and ultraviolet light To polymerize the polymerizable composition to memorize the alignment state of the liquid crystal as a cured product. At present, the PSA principle is used in various conventional liquid crystal display devices. Thus, for example, PSA-VA, PSA-OCB, PS-IPS / FFS- and PS-TN-display devices are known.

However, the group consisting of the liquid crystal composition and the polymerizable compound are not all applied to the PSA display element. Thus, for example, it can not be adjusted to obtain tilting or sufficient tilting, or is insufficient for application to TFT displays due to, for example, the so-called " voltage holding ratio " (VHR). In addition, it has been discovered that, when used in PSA display devices, there are still some defects in the liquid crystal compositions and polymerizable compounds known in the prior art. Thus, polymeric compounds soluble in all known liquid crystal compositions are not applicable to PSA displays. The liquid crystal compositions and polymeric compounds selected have as good electrical properties as possible and, in particular, have the highest VHR. In PSA display devices, in particular, high VHR after UV light is required.

As a problem of such a liquid crystal display device, there is a problem of reliability such as " burning " which occurs when the same display is continuously operated for a long time, and productivity due to manufacturing process. The reliability problem is not a single problem, but is caused by various complex factors, especially due to the change in the slope of the liquid crystal molecules (the change in the pretilt angle).

It is an object of the present invention to provide a novel material to be applied to a PSA liquid crystal display device, and in particular, a combination of a liquid crystal composition and a polymerizable compound is applied to solve the above problems. When applied to a PSA type liquid crystal display device, Can be overcome. The combination of the liquid crystal composition and the polymerizable compound provided in the present invention has a relatively high temperature range, at the same time, has suitable dielectric anisotropy, suitable optical anisotropy, and also has a high VHR value after exposure to UV. When using a combination comprising the liquid crystal composition of the present invention and a polymerizable compound, it has the characteristics of producing good anti-UV performance and faster pre-sharpening angle compared with existing techniques.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a liquid crystal composition having a suitable optical anisotropy, a suitable dielectric anisotropy, a relatively high transparency, a good anti-UV stability and a high ability to form a pretilt angle. The liquid crystal composition can be applied to a liquid crystal display, the liquid crystal display has high reliability, and has properties to normally operate after irradiating UV light. The liquid crystal composition provided in the present invention has a more excellent ability to form a square, and the polymer is stably and vertically oriented to have a better optical effect by displaying the device. Also, after the liquid crystal composition of the present invention is irradiated with UV light Has a relatively good VHR value, and has better stability using the liquid crystal display element of the liquid crystal composition of the present invention.
