Abstract
A liquid crystal display device includes: a liquid crystal panel; a first polarizing film and a second polarizing film on a bottom surface and a top surface, respectively, of the liquid crystal panel; a backlight unit below the first polarizing film; and a titanium oxide film on the second polarizing film and that transmits one of right-handed circularly polarized light and left-handed circularly polarized light and reflects the other, with a predetermined wavelength, of the right-handed circularly polarized light and the left-handed circularly polarized light.

A liquid crystal display device, comprising:
- a liquid crystal panel;
- a first polarizing film and a second polarizing film on a bottom surface and a top surface, respectively, of the liquid crystal panel;
- a backlight unit below the first polarizing film;
- and
- a titanium oxide film directly formed on the second polarizing film and that transmits one of right-handed circularly polarized light and left-handed circularly polarized light and reflects the other, with a predetermined wavelength, of the right-handed circularly polarized light and the left-handed circularly polarized light.
