Nematic liquid crystal composition, and liquid crystal display element using same

[0247] Hereinafter, examples are given and the present invention will be described in further detail, but the present invention is not limited to these examples. In addition, "%" in the composition of a following Example and a comparative example means "mass %".

[0248] The following abbreviations are used for descriptions of compounds in Examples.

[0249] (side chain)

[0250] -n -C n h 2n+1 straight-chain alkyl group with carbon number n

[0251] n-C n h 2n+1 - Straight-chain alkyl group with carbon number n

[0252] -On -OC n h 2n+1 straight-chain alkoxyl with carbon number n

[0253] nO-C n h 2n+1 O- straight-chain alkoxy with carbon number n

[0254] -V -CH=CH 2

[0255] V-CH 2 =CH-

[0256] -V1 -CH=CH-CH 3

[0257] 1V-CH 3 -CH=CH-

[0258] -2V -CH 2 -CH 2 -CH=CH 3

[0259] V2-CH 3 =CH-CH 2 -CH 2 -

[0260] -2V1-CH 2 -CH 2 -CH=CH-CH 3

[0261] 1V2-CH 3 -CH=CH-CH 2 -CH 2 -

[0262] (connecting group)

[0263] -CF2O- -CF 2 -O-

[0286] In addition, a liquid crystal display device in PSVA mode was produced using a liquid crystal composition obtained by adding 0.3 mass % of formula (XX-4) as a polymerizable compound to 99.7 mass % of each liquid crystal composition of LC-1 to LC-4. None of the elements exhibited a defect, and sufficient high-speed response was confirmed.

[0288] Using a liquid crystal composition obtained by adding 0.35% by mass of a compound of formula (XX-2) as a polymerizable compound to 99.65% by mass of liquid crystal composition LC-A, a PSVA mode liquid crystal display element was produced, and a burn-in phenomenon was observed.
