Description
Technical field
The present invention relates to a kind of liquid-crystal composition, and specifically, liquid-crystal composition provided by the present invention has negative Jie
Electrical anisotropy；More precisely, contain dibenzofurans class compound in liquid-crystal composition provided by the present invention.
Background technology
At present, liquid crystal is widely applied in field of information display, while the application in optical communication also achieves one
Fixed progress (S.T.Wu, D.K.Yang.Reflective Liquid Crystal Displays.Wiley, 2001).It is near several
Year, the application field of liquid-crystal compounds significantly widens kinds of displays part, electro-optical device, electronic component, sensor etc.,
Nematic liquid crystal compound obtains most commonly used application in flat-panel monitor, particularly for tft active matrix
In system.
At present, negative liquid crystal is widely used in large-sized TV liquid crystal display, especially the appearance of PSVA technologies,
So that negative liquid crystal is more welcome；In recent years, the display of the mobile device such as mobile phone widely uses negative liquid crystal FFS and shown
Device, because it has high transmitance, the energy that LCD backlight is consumed can be greatly reduced, lift the aobvious of liquid crystal display
Show quality, extend the cruising time of mobile device.
Negative liquid crystal most proposes that it is mainly used in VA patterns, and its major advantage is to contrast earlier than the end of the eighties in last century
Degree is high, and major defect is that visual angle is small, and the response time is slow.As the technologies such as the development of Display Technique, MVA, PVA, PSVA go out in succession
It is existing, solve the problems, such as response time and visual angle.In recent years, as touch-screen turns into the mobile device market mainstream, IPS and FFS
The hard panel type display of class has inborn advantage, IPS and FFS class displays can both use positivity liquid crystal, can also use negativity
Liquid crystal, due to bending electric field present in the class display, positivity liquid crystal arranges along electric field line direction, so as to cause molecule curved
Song, and decline in transmitance；Negative liquid crystal arranges perpendicular to electric field line direction, thus transmitance can be substantially improved, and be current
Lift transmitance, reduce backlight power consumption the best way.But response time problem existing for negative liquid crystal is the weight currently encountered
Hang-up, using negative liquid crystal FFS displays relative to positivity liquid crystal FFS display response times slow 50% or more.
Therefore, how to lift the response time of negative liquid crystal turns into current key problem.
Specifically, the response time of liquid crystal display depends on d2·γ1/Keff(d is thickness of liquid crystal layer, and γ 1 is liquid crystal
Rotary viscosity, KeffFor effective elastic constant), therefore, rotary viscosity reduced, reduce thickness of liquid crystal layer and lift elastic constant and be equal
Can reach improves the purpose of response time.
