Display device
The present invention provides a display device which can reduce reflected light reflected on the respective surfaces of a display panel and a protective plate, even if the protective plate is disposed on the surface of the display panel, without employing a complicated structure and without degrading display quality. The display device includes: a display panel; and a protective plate disposed facing the display panel. The protective plate has a protective base material and a first polarizer, the display panel has a second polarizer of which a polarization axis is parallel to that of the first polarizer, and light passing between the first polarizer and the second polarizer is linearly polarized light.
1. A display device, comprising:
a display panel; and
a protective plate disposed facing the display panel,
wherein the protective plate comprises a protective base material and a first polarizer,
wherein the display panel comprises a second polarizer of which a polarization axis is parallel to that of the first polarizer,
light passing between the first polarizer and the second polarizer is linearly polarized light, and
nothing to substantially convert a light polarization state is disposed between the first polarizer and the second polarizer.
2. The display device according to claim 1 , wherein an air layer is disposed between the display panel and the protective plate.
3. The display device according to claim 1 , wherein the first polarizer is disposed on the display panel side of the protective base material.
4. The display device according to claim 1 , wherein the protective plate further comprises a first antireflection layer on the display panel side surface of the protective plate.
5. The display device according to claim 1 , wherein the display panel further comprises a second antireflection layer on the protective plate side surface of the display panel.
6. The display device according to claim 1 , wherein the protective plate further comprises a third antireflection layer on the surface, facing the outside, of the protective plate.
7. The display device according to claim 1 , wherein the display panel has a third polarizer, a first substrate, a liquid crystal layer, a second substrate, and the second polarizer, in this order toward the protective plate.
8. The display device according to claim 1 , wherein the display panel has a first electrode, an organic electroluminescence layer, a second electrode, a λ/4 plate, and the second polarizer, in this order toward the protective plate.
