Description

液晶組成物及び液晶表示素子Liquid crystal composition and liquid crystal display element
 本願発明は、誘電率異方性が正又は負のネマチック液晶組成物を用い、高透過率、高開口率に特徴を有する液晶表示装置に関する。 The present invention relates to a liquid crystal display device using a nematic liquid crystal composition having a positive or negative dielectric anisotropy and characterized by high transmittance and high aperture ratio.
 液晶表示素子は、時計、電卓をはじめとして、各種測定機器、自動車用パネル、ワードプロセッサー、電子手帳、プリンター、コンピューター、テレビ、時計、広告表示板等に用いられるようになっている。液晶表示方式としては、その代表的なものにTN(ツイステッド・ネマチック)型、STN(スーパー・ツイステッド・ネマチック)型、TFT(薄膜トランジスタ)を用いた垂直配向型やIPS(イン・プレーン・スイッチング)型等がある。 Liquid crystal display elements are used in various measuring instruments, automobile panels, word processors, electronic notebooks, printers, computers, televisions, watches, advertisement display boards, etc., including clocks and calculators. Typical liquid crystal display methods include TN (twisted nematic) type, STN (super twisted nematic) type, vertical alignment type using TFT (thin film transistor), and IPS (in-plane switching) type. Etc.
 近年、液晶TVの高解像度化が進み、既に8Kの解像度を有する製品が多数開発されている。高解像度化が進んでも、TV全体のサイズが大きくなるとは限らず、結果として一つの画素のサイズは高解像度化に従って、縮小されることとなる。これによる透過率の低下による輝度の低下を補填するためには、より輝度の高いバックライトを必要とし、このようなバックライトは必然的に消費電力の上昇を招き、近年の強い省電力化の要求に応えられなくなってきている。また、開口率を向上させるために、画素電極幅を小さく作成することによる液晶組成物に対する新たな要求も生じてきた。 In recent years, the resolution of liquid crystal TVs has been increased, and many products having a resolution of 8K have already been developed. Even if the resolution is increased, the size of the entire TV is not necessarily increased. As a result, the size of one pixel is reduced as the resolution is increased. In order to compensate for the decrease in luminance due to the decrease in transmittance, a backlight with higher luminance is required. Such a backlight inevitably causes an increase in power consumption. It is becoming impossible to meet the demand. In addition, in order to improve the aperture ratio, there has been a new demand for a liquid crystal composition by making the pixel electrode width small.
 これらに加え、液晶組成物に対し、水分、空気、熱、光などの外的刺激に対して安定であること、また、室温を中心としてできるだけ広い温度範囲で液晶相を示し、低粘性であり、かつ駆動電圧が低いことが求められる。これら要求を満たすために液晶組成物は、誘電率異方性(Δε)又は及び屈折率異方性(Δn)等を個々の表示素子にとって最適な値とするために、数種類から数十種類の化合物を用い構成されている。 In addition to these, the liquid crystal composition is stable against external stimuli such as moisture, air, heat, light, etc., and exhibits a liquid crystal phase in the widest possible temperature range centering on room temperature, and has low viscosity. And a low driving voltage is required. In order to satisfy these requirements, the liquid crystal composition has several to several tens of kinds in order to make the dielectric anisotropy (Δε) or the refractive index anisotropy (Δn) optimum values for individual display elements. It is composed of compounds.
 全ての駆動方式において低電圧駆動、高速応答、広い動作温度範囲が求められており、Δεが正又は負で絶対値が大きく、粘度(η)が小さく、高いネマチック相-等方性液体相転移温度(Tni)が要求されている。また、Δnとセルギャップ(d)との積であるΔn×dの設定から、液晶組成物のΔnをセルギャップに合わせて適当な範囲に調節する必要がある。加えて液晶表示素子をテレビ等へ応用する場合においては高速応答性が重視されるため、回転粘性(γ1)の小さい液晶組成物が要求される。 All drive systems require low-voltage drive, high-speed response, and a wide operating temperature range. Δε is positive or negative, large absolute value, low viscosity (η), high nematic phase to isotropic liquid phase transition. Temperature (Tni) is required. Further, from the setting of Δn × d, which is the product of Δn and the cell gap (d), it is necessary to adjust Δn of the liquid crystal composition to an appropriate range according to the cell gap. In addition, when applying a liquid crystal display element to a television or the like, since high-speed response is important, a liquid crystal composition having a low rotational viscosity (γ1) is required.
 高速応答性を志向した液晶組成物の構成として、例えば、Δεが正の液晶化合物及びΔεが中性の液晶化合物を組み合わせて使用した液晶組成物の開示がされている(特許文献1から4)。 As a configuration of a liquid crystal composition aimed at high-speed response, for example, a liquid crystal composition using a combination of a liquid crystal compound having a positive Δε and a liquid crystal compound having a neutral Δε is disclosed (Patent Documents 1 to 4). .
 高速応答性を志向した液晶組成物の構成として、例えば、Δεが負の液晶化合物及びΔεが中性の液晶化合物を組み合わせて使用した液晶組成物の開示がされている(特許文献5から7)。 As a configuration of a liquid crystal composition intended for high-speed response, for example, liquid crystal compositions using a combination of a liquid crystal compound having a negative Δε and a liquid crystal compound having a neutral Δε are disclosed (Patent Documents 5 to 7). .

 本発明が解決しようとする課題は、Δεが正の組成物であって、広い温度範囲の液晶相を有し、粘性が小さく、低温での溶解性が良好で、比抵抗や電圧保持率が高く、熱や光に対して安定な組成物を提供し、更にこれを用いることで表示品位に優れ、焼き付きや滴下痕等の表示不良の発生し難いFFS型、IPS型やTN型等の液晶表示素子を歩留まりよく提供することにある。 The problem to be solved by the present invention is a composition having a positive Δε, a liquid crystal phase in a wide temperature range, low viscosity, good solubility at low temperature, specific resistance and voltage holding ratio. A liquid composition such as FFS, IPS, or TN type that provides a high and stable composition against heat and light, and has excellent display quality by using this composition, and display defects such as image sticking and dripping marks are difficult to occur. The object is to provide display elements with high yield.

 本発明の重合性化合物を含有した組成物は、これに含まれる重合性化合物が紫外線照射により重合することで液晶配向能が付与され、組成物の複屈折を利用して光の透過光量を制御する液晶表示素子に使用される。 In the composition containing the polymerizable compound of the present invention, the polymerizable compound contained therein is polymerized by ultraviolet irradiation to impart liquid crystal alignment ability, and the amount of transmitted light is controlled using the birefringence of the composition. Used for liquid crystal display elements.
 本発明の液晶組成物が重合性化合物を含有する場合、重合性化合物を重合させる方法としては、液晶の良好な配向性能を得るためには、適度な重合速度が望ましいので、紫外線又は電子線等の活性エネルギー線を単一又は併用又は順番に照射することによって重合させる方法が好ましい。紫外線を使用する場合、偏光光源を用いても良いし、非偏光光源を用いても良い。また、重合性化合物含有組成物を2枚の基板間に挟持させて状態で重合を行う場合には、少なくとも照射面側の基板は活性エネルギー線に対して適当な透明性が与えられていなければならない。また、光照射時にマスクを用いて特定の部分のみを重合させた後、電場や磁場又は温度等の条件を変化させることにより、未重合部分の配向状態を変化させて、更に活性エネルギー線を照射して重合させるという手段を用いても良い。特に紫外線露光する際には、重合性化合物含有組成物に交流電界を印加しながら紫外線露光することが好ましい。印加する交流電界は、周波数10Hzから10kHzの交流が好ましく、周波数60Hzから10kHzがより好ましく、電圧は液晶表示素子の所望のプレチルト角に依存して選ばれる。つまり、印加する電圧により液晶表示素子のプレチルト角を制御することができる。横電界型MVAモードの液晶表示素子においては、配向安定性及びコントラストの観点からプレチルト角を80度から89.9度に制御することが好ましい。 When the liquid crystal composition of the present invention contains a polymerizable compound, an appropriate polymerization rate is desirable for obtaining a good alignment performance of the liquid crystal as a method for polymerizing the polymerizable compound, such as ultraviolet rays or electron beams. A method in which the active energy rays are polymerized by irradiating them in a single or a combination or sequentially. When ultraviolet rays are used, a polarized light source or a non-polarized light source may be used. Further, when the polymerization is carried out in a state where the polymerizable compound-containing composition is sandwiched between two substrates, at least the substrate on the irradiated surface side must be given adequate transparency to the active energy rays. Don't be. Moreover, after polymerizing only a specific part using a mask during light irradiation, the orientation state of the unpolymerized part is changed by changing conditions such as an electric field, a magnetic field, or temperature, and further irradiation with active energy rays is performed. Then, it is possible to use a means for polymerization. In particular, when ultraviolet exposure is performed, it is preferable to perform ultraviolet exposure while applying an alternating electric field to the polymerizable compound-containing composition. The alternating electric field to be applied is preferably an alternating current having a frequency of 10 Hz to 10 kHz, more preferably a frequency of 60 Hz to 10 kHz, and the voltage is selected depending on a desired pretilt angle of the liquid crystal display element. That is, the pretilt angle of the liquid crystal display element can be controlled by the applied voltage. In a horizontal electric field type MVA mode liquid crystal display element, the pretilt angle is preferably controlled from 80 degrees to 89.9 degrees from the viewpoint of alignment stability and contrast.

The intensity of the irradiated ultraviolet light is preferably 0.1 mW / cm 2 to 100 W / cm 2, more preferably 2 mW / cm 2 to 50 W / cm 2.

Further, when the polymerization is carried out in a state where the polymerizable compound-containing composition is sandwiched between two substrates, at least the substrate on the irradiated surface side must be given adequate transparency to the active energy rays.

Moreover, after polymerizing only a specific part using a mask during light irradiation, the orientation state of the unpolymerized part is changed by changing conditions such as an electric field, a magnetic field, or temperature, and further irradiation with active energy rays is performed.
