Liquid crystal display device

A liquid crystal display device, comprising:

• a first substrate;
• a second substrate;
• and
• a liquid crystal composition disposed between said first substrate and said second substrate,
• wherein said first substrate and said second substrate are disposed in parallel and opposite to each other, with a distance between said first substrate and said second substrate being 2.5 μm to 3.2 μm;
• two alignment layers are independently disposed on a side of said first and second substrates that faces to said liquid crystal composition;
• said alignment layers are provided with vertical alignment films that allow liquid crystal molecules in said liquid crystal composition to be arranged roughly perpendicular to said first or second substrate;
• and
• said liquid crystal composition comprises one or more compounds represented by formula I below, one or more compounds represented by formula II below, and one or more compounds represented by formula VI below:
• wherein R0 represents an alkyl group having a carbon atom number of 1-10, an alkoxy group having a carbon atom number of 1-10, an alkenyl group having a carbon atom number of 2-10, or an alkenoxy group having a carbon atom number of 3-8, and R1 represents an alkenyl group having a carbon atom number of 2-10;
• and
• wherein R3 and R4 each independently represent an alkyl group having a carbon atom number of 1-10, a fluorine-substituted alkyl group having a carbon atom number of 1-10, an alkoxy group having a carbon atom number of 1-10, a fluorine-substituted alkoxy group having a carbon atom number of 1-10, an alkenyl group having a carbon atom number of 2-10, a fluorine-substituted alkenyl group having a carbon atom number of 2-10, an alkenoxy group having a carbon atom number of 3-8 or a fluorine-substituted alkenoxy group having a carbon atom number of 3-8, and any one or more non-neighboring —CH2— in the groups represented by R3 and R4 are each independently optionally substituted with cyclopentylene, cyclobutylene or cyclopropylene;
• wherein R9 and R10 each independently represent an alkyl group having a carbon atom number of 1-10, a fluorine-substituted alkyl group having a carbon atom number of 1-10, an alkoxy group having a carbon atom number of 1-10, a fluorine-substituted alkoxy group having a carbon atom number of 1-10, an alkenyl group having a carbon atom number of 2-10, a fluorine-substituted alkenyl group having a carbon atom number of 2-10, an alkenoxy group having a carbon atom number of 3-8 or a fluorine-substituted alkenoxy group having a carbon atom number of 3-8, and any one or more non-neighboring —CH2— groups in the groups represented by R9 and R10 are each independently optionally substituted with cyclopentylene, cyclobutylene or cyclopropylene;
• X represents O, S or —CH2O—;
• Z1 and Z2 each independently represent a single bond, —CH2CH2— or —CH2O—;
• each independently represent 1,4-phenylene, 1,4-cyclohexylene, fluorinated 1,4-phenylene or 1,4-cyclohexenylene;
• m represents 1 or 2;
• and
• n represents 0, 1 or 2.
