Abstract
Provided is a display device with enhanced uniformity of brightness. The display device includes a display panel, and a backlight unit configured to supply light to the display panel, wherein the display panel includes a liquid crystal panel with first and second surfaces opposite to each other, a first polarizing plate arranged on the first surface of the liquid crystal panel, a second polarizing plate arranged on the second surface of the liquid crystal panel, a light absorbing layer arranged on the second polarizing plate to absorb a portion of the light supplied from the backlight unit, and a light absorbing material included in the light absorbing layer to absorb light of particular wavelengths.
Claims19
A display device comprising:
- a display panel;
- and
- a backlight unit configured to supply light to the display panel,
- wherein the display panel comprises:
- a liquid crystal panel comprising a first surface and a second surface that is opposite to the first surface;
- a first polarizing plate provided on the first surface of the liquid crystal panel;
- a second polarizing plate provided on the second surface of the liquid crystal panel;
- a light absorbing layer provided on the second polarizing plate, the light absorbing layer being configured to absorb a portion of the light supplied from the backlight unit;
- and
- a light absorbing material included in the light absorbing layer and configured to absorb light of predetermined wavelengths.
A display device comprising:
- a display panel;
- and
- a backlight unit configured to supply light to the display panel,
- wherein the display panel comprises
- a liquid crystal panel comprising a first surface and a second surface that is opposite to the first surface;
- a first polarizing plate provided on the first surface of the liquid crystal panel;
- a second polarizing plate provided on the second surface of the liquid crystal panel;
- a light absorbing layer provided on the second polarizing plate, the light absorbing layer comprising:
- a first resin layer;
- a second resin layer having a refractive index that is different than a refractive index of the first resin layer;
- and
- light absorbers provided on the first resin layer and configured to absorb a portion of light passing the light absorbing layer;
- and
- a light absorbing material included in at least one from among the first resin layer, the second resin layer, and the light absorbers and configured to absorb light of predetermined wavelengths.
A display device comprising:
- a display panel;
- and
- a backlight unit configured to supply light to the display panel,
- wherein the display panel comprises:
- a liquid crystal panel;
- a first polarizing plate provided on the liquid crystal panel;
- a second polarizing plate provided on the liquid crystal panel opposite to the first polarizing plate;
- a light absorbing layer provided on the second polarizing plate, the light absorbing layer being configured to absorb light inclined at more than a predetermined angle from a baseline extending in a front-back direction of a surface of the display panel among light incident on the light absorbing layer;
- and
- a light absorbing material included in the light absorbing layer and configured to absorb light of predetermined wavelengths.
