Abstract
The present invention provides a liquid crystal horizontal orientation agent, a horizontal orientation type liquid crystal composition, a horizontal orientation type LCD device and a method of fabricating the horizontal orientation type LCD device. In one embodiment, the liquid crystal molecule is horizontally oriented by the liquid crystal horizontal orientation agent without the rubbed orientation layer.
Claims16
A liquid crystal horizontal orientation agent, comprising:
- a core;
- and
- a dendrimer including a dendron part linked with the core.
A horizontal orientation type liquid crystal composition, comprising:
- a liquid crystal component;
- and
- a liquid crystal horizontal orientation agent including:
- a core;
- and
- a dendrimer including a dendron part linked with the core.
A horizontal orientation type liquid crystal display device, comprising:
- a first substrate including comb-shaped electrodes;
- a second substrate facing the first substrate;
- and
- a liquid crystal layer including a liquid crystal component and a liquid crystal horizontal orientation agent, the liquid crystal horizontal orientation agent including a core;
- and a dendrimer including a dendron part linked with the core,
- wherein a polarized UV ray is irradiated to the liquid crystal layer such that a liquid crystal molecule in the liquid crystal layer is horizontally oriented with respect to the first and second substrates.
A method of fabricating a horizontal orientation type liquid crystal display device, comprising:
- forming comb-shaped electrodes on a first substrate;
- attaching a second substrate with the first substrate;
- forming a liquid crystal layer including a liquid crystal component and a liquid crystal horizontal orientation agent, the liquid crystal horizontal orientation agent including a core, and a dendrimer including a dendron part linked with the core;
- and
- irradiating a polarized UV ray to the liquid crystal layer.
