Abstract

A liquid crystal display device includes a transmissive liquid crystal panel having a first surface and a second surface opposite the first surface, a first polarizing film arranged on a side of the first surface of the transmissive liquid crystal panel, a second polarizing film arranged on an opposite side of the first polarizing film from the transmissive liquid crystal panel, and a third polarizing film arranged on a side of the second surface of the transmissive liquid crystal panel. An absorption axis of the first polarizing film is arranged parallel to an initial alignment direction of liquid crystal molecules included in the transmissive liquid crystal panel, the first polarizing film and the third polarizing film are arranged in a crossed Nicol manner, and an absorption axis of the second polarizing film is inclined with respect to the absorption axis of the first polarizing film.

Claims (19)

1 . A liquid crystal display device, comprising:

a transmissive liquid crystal panel having a first surface and a second surface opposite the first surface;

a first polarizing film arranged on a side of the first surface of the transmissive liquid crystal panel;

a second polarizing film arranged on an opposite side of the first polarizing film from the transmissive liquid crystal panel; and

a third polarizing film arranged on a side of the second surface of the transmissive liquid crystal,

wherein

an absorption axis of the first polarizing film is arranged parallel to an initial alignment direction of liquid crystal molecules included in the transmissive liquid crystal panel,

the first polarizing film and the third polarizing film are arranged in a crossed Nicol manner, and

an absorption axis of the second polarizing film is inclined with respect to the absorption axis of the first polarizing film.

2 . The liquid crystal display device according to claim 1 , wherein the absorption axis of the second polarizing film is inclined at an angle of more than 0 degrees and 45 degrees or less with respect to the absorption axis of the first polarizing film.

3 . The liquid crystal display device according to claim 1 , further comprising a retardation film arranged on an opposite side of the second polarizing film from the first polarizing film,

wherein a stretching axis of the retardation film is inclined at a predetermined angle with respect to the absorption axis of the second polarizing film.

4 . The liquid crystal display device according to claim 3 , wherein the retardation film is a ¼-wavelength retardation film.

5 . The liquid crystal display device according to claim 1 , further comprising a retardation film between the first polarizing film and the second polarizing film,

wherein a first direction of a stretching axis of the retardation film is between a second direction of the absorption axis of the first polarizing film and a third direction of the absorption axis of the second polarizing film.

6 . The liquid crystal display device according to claim 5 , wherein the retardation film is a ½-wavelength retardation film.

7 . The liquid crystal display device according to claim 5 , wherein the first direction is intermediate between the second direction and the third direction.

8 . The liquid crystal display device according to claim 1 , wherein the transmissive liquid crystal panel is an IPS liquid crystal panel or a TN liquid crystal panel.

9 . A head mounted display comprising the liquid crystal display device according to claim 1 .
