Embodiment 1
[0082] [Preparation of liquid crystal composition]
[0083] 0.3 parts by weight of the compound represented by the above formula (M-1-1) was mixed and dissolved in 99.7 parts by weight of negative liquid crystals (manufactured by Melku, trade name "MLC-6608") to prepare a liquid crystal composition.
[0084] [Preparation of Liquid Crystal Display Element]
[0085] On the transparent electrode surface of a glass substrate with a transparent electrode made of an ITO film, a spin coater was used to apply a commercially available "AL60101" (manufactured by JSR Co., Ltd.) as a liquid crystal aligning agent, and pre-processed with a hot plate at 80°C. After baking for 1 minute, in an oven in which the chamber was replaced with nitrogen, post-baking at 200°C for 1 hour to form an organic film with a film thickness of 0.1 μm. Repeat the same operation to obtain a pair (two pieces) of substrates with a transparent electrode and an organic film on one side in sequence.

Embodiment 2
[0097] 0.3 parts by weight of the compound represented by the above formula (M-1-2) was mixed with 99.7 parts by weight of negative liquid crystals (manufactured by Melku, trade name "MLC-6608") to prepare a liquid crystal composition.
[0098] Except for using this liquid crystal composition, a liquid crystal display element was manufactured and evaluated in the same manner as in Example 1. The liquid crystal orientation of the liquid crystal display element was "good" and the voltage retention ratio was "good".
[0099] The liquid crystal display elements manufactured in the above-mentioned Examples 1 and 2 each exhibited good liquid crystal orientation and good viewing angle characteristics. This liquid crystal display element does not need to use complicated-shaped electrodes in order to determine the orientation direction of the liquid crystal, and therefore can be manufactured at very low cost compared with the liquid crystal display elements described in Patent Documents 2 an...
Embodiment 3
[0101] In the above Example 1, in addition to using the commercially available "AL60101" as a liquid crystal aligning agent, the compound represented by the above formula (1) was added at a solid content ratio of 0.1% by weight, and the irradiation dose of polarized light rays was 10J / cm 2 Other than that, it carried out similarly to Example 1, and produced and evaluated a liquid crystal display element. The liquid crystal orientation of this liquid crystal display element was "good", and the voltage retention ratio was "good".
