Liquid crystal display element, liquid crystal display device using the same, and image display method

A liquid crystal display device, comprising:

• a first substrate having a first electrode on one surface thereof;
• a transparent second substrate having a transparent second electrode on one surface thereof and being opposed to the first substrate such that the first electrode and the transparent second electrode are opposed to each other;
• a first liquid crystal layer containing a first liquid crystal composition and disposed between the first substrate and the transparent second substrate;
• a color filter disposed between the first substrate and the transparent second substrate, the color filter being at a transparent second substrate side of the first liquid crystal layer;
• a second liquid crystal layer containing a second liquid crystal composition and disposed between the first substrate and the transparent second substrate, the second liquid crystal layer being at a transparent second substrate side of the color filter, and the dielectric constant of the second liquid crystal layer being different from that of the first liquid crystal layer;
• and
• a voltage applying device that applies voltage between the first electrode and the transparent second electrode,
• at least one of the first and second liquid crystal layers comprising an additive having dielectric properties.

An image display method, comprising:

• applying a voltage to a liquid crystal display element that comprises:
• a first substrate having a first electrode on one surface thereof,
• a transparent second substrate having a transparent second electrode on one surface thereof and being opposed to the first substrate such that the first electrode and the transparent second electrode are opposed to each other,
• a first liquid crystal layer containing a liquid crystal composition and disposed between the first substrate and the transparent second substrate,
• a color filter disposed between the first substrate and the transparent second substrate, the color filter being at a transparent second substrate side of the first liquid crystal layer, and
• a second liquid crystal layer containing a liquid crystal composition and disposed between the first substrate and the transparent second substrate, the second liquid crystal layer being at a transparent second substrate side of the color filter, the dielectric constant of the second liquid crystal layer being different from that of the first liquid crystal layer,
• at least one of the first and second liquid crystal layers comprising an additive having dielectric properties;
• and
• controlling the value of the voltage applied between the first electrode and the transparent second electrode to display an image in a desired color.
