Abstract
A liquid crystal display device capable of improving a contrast ratio is provided. The device includes a first substrate including a first alignment film and a first polarizing film having a first transmission axis parallel to an alignment direction of the first alignment film, a second substrate including a second alignment film and a second polarizing film having a second transmission axis perpendicular to the first transmission axis of the first polarizing film, and a liquid crystal layer between the first and second substrates, the liquid crystal layer including a dichroic dye, wherein the liquid crystal is aligned in horizontal direction.
Claims12
A liquid crystal display device comprising:
- a first substrate including a first alignment film and a first polarizing film having a first transmission axis parallel to an alignment direction of the first alignment film;
- a second substrate including a second alignment film and a second polarizing film having a second transmission axis perpendicular to the first transmission axis of the first polarizing film;
- and
- a liquid crystal layer between the first and second substrates, the liquid crystal layer including a dichroic dye,
- wherein liquid crystal molecules are aligned in a horizontal direction when a voltage is applied to the liquid crystal layer, and when the voltage is not applied to the liquid crystal layer, the dichroic dye is aligned parallel to the liquid crystal molecules included in the liquid crystal layer and absorbs a part of a linearly polarized light from the first polarizing film.
