Description

Composition and use its liquid crystal display cells

Technical field

The present invention relates to as liquid crystal display material it is useful dielectric constant anisotropy (Δ ε) display on the occasion of composition And use its liquid crystal display cells.

Background technology

Liquid crystal display cells are developed into for various sensing equipments, automobile panel, word since clock, calculator Processor, electronic notebook, printer, computer, television set, clock, advertising display panel etc..It is used as liquid crystal display mode, its generation Table mode have TN (twisted-nematic) type, STN (super twisted nematic) type, the vertical orientating type using TFT (thin film transistor (TFT)), IPS (plane conversion) type etc..Liquid-crystal composition requirement used in these liquid crystal display cells is to moisture, empty air and heat, light etc. Environmental stimuli is stable, in addition, liquid crystalline phase is showed within the scope of temperature as wide as possible centered on room temperature, low viscosity, and drive Dynamic voltage is low.Further, in order to for each display element by dielectric constant anisotropy (Δ ε) or and refractive anisotrop (Δ n) etc. is set to most just when liquid-crystal composition is made up of several to tens of kinds of compounds.

The use of Δ ε is negative liquid-crystal composition in vertical orientated (VA) escope, it is (flat in TN types, STN types or IPS Change in face) the use of Δ ε is positive liquid-crystal composition in the horizontal alignment escope such as type.In addition, also reporting makes Δ ε for just Liquid-crystal composition it is vertical orientated in no applied voltage, the type of drive shown by applying transverse electric field so that Δ ε further improves for the necessity of positive liquid-crystal composition.On the other hand, in all type of drive, it is required to low-voltage Driving, high-speed response, wide operating temperature range.I.e., it is desirable to Δ ε for just and absolute value is big, viscosity (η) is small, high nematic phase-each to Same sex liquid phase transition temperature (Tni).In addition, it is contemplated that the product of Δ n and cell gap (d) is Δ n × d setting, it is necessary to tie Cell gap is closed to adjust the Δ n of liquid-crystal composition to appropriate scope.In addition, liquid crystal display cells are being applied to electricity In the case of machine etc., pay attention to high-speed response, therefore it is required that the small liquid-crystal composition of rotational viscosity (γ 1).

As pursue high-speed response liquid-crystal composition composition, disclose for example using as Δ ε be positive liquid-crystalization Compound represented by the formula (A-1) of compound, (A-2) and the liquid being applied in combination as Δ ε for (B) of neutral liquid-crystal compounds Crystal composite (patent document 1 to 4).

[changing 1]

On the other hand, expand with the purposes of liquid crystal display cells, its application method, manufacture method can also see that big change Change.In order to tackle these changes, it is desirable to by the characteristic optimization beyond in the past known basic physical properties value.That is, using liquid crystal group The liquid crystal display cells of compound are used to following degree：VA types, IPS types etc. are widely used, and its size is more than 50 types The display element of ultra-large type size is practical.With the maximization of substrate size, method for implanting from liquid-crystal composition to substrate Also it is changed into instillation (ODF from conventional vacuum impregnation：One Drop Fill) method and as method for implanting main flow, but will The drop impression that liquid-crystal composition is dripped when substrate causes the problem of display quality is reduced significantly to be changed.Further, in the liquid using ODF methods In crystal display element manufacturing process, it is necessary to most suitable liquid crystal injection rate of being dripped according to the size of liquid crystal display cells.If Injection rate and most just when deviation become big, then the refractive index for the liquid crystal display cells being pre-designed, the balance of driving electric field can collapse Burst, occur the displays such as the generation of spot, contrast be bad bad.Especially it is used for small-sized in the smart mobile phone of nearest prevalence Liquid crystal display cells, because most suitable liquid crystal injection rate is few, therefore by and most just when deviation control within the specific limits itself It is difficult.Therefore, in order to keep the yield rates of liquid crystal display cells higher, in addition it is also necessary to following performance：For example, to liquid crystal drop The influence of abrupt pressure change, impact when lower in caused dripping device is small, and can persistently drip liquid long-term and stably It is brilliant.

So, for liquid crystal group used in the driven with active matrix liquid crystal display cells that are driven with TFT elements etc. Compound, it is desirable to consider the exploitation after following aspect：Maintain high speed response property etc. as the characteristic required by liquid crystal display cells, Performance, and with the high resistivity value or high voltage holding ratio just paid attention in the past, it is stable to outside stimulus such as light, heat such Characteristic, and liquid crystal display cells manufacture method.
