Cover panel and display device
A cover panel according to the present disclosure includes a first reflection suppressing film and a first polarizing plate. The first polarizing plate is arranged between the first reflection suppressing film and a liquid crystal panel. The first polarizing plate polarizes light. The cover panel further includes at least one of a louver layer and a decorative layer. The louver layer includes light transmitting members and light absorbing members repeatedly arranged between the first reflection suppressing film and the first polarizing plate. The light transmitting members transmits light. The light absorbing members absorbs light. The decorative layer has a pattern. The cover panel is arranged to be separated from a liquid crystal panel.
1. A cover panel comprising:
a first reflection suppressing film; and
a first polarizing plate that is arranged between the first reflection suppressing film and a liquid crystal panel, and polarizes light, and
further comprising a louver layer, the louver layer including light transmitting members and light absorbing members repeatedly arranged between the first reflection suppressing film and the first polarizing plate, the light transmitting members transmitting light, the light absorbing members absorbing light, wherein
the cover panel is spaced apart from the liquid crystal panel by an air layer,
the first polarizing plate is arranged between the air layer and the louver layer, and
the louver layer is bonded to the first polarizing plate by an adhesive layer.
2. The cover panel according to claim 1 , further comprising a light-shielding frame that is arranged between the louver layer, and the liquid crystal panel, and overlaps a peripheral portion of the first polarizing plate when transparently viewed from a direction perpendicular to a front surface of the first reflection suppressing film.
3. The cover panel according to claim 2 , wherein the light-shielding frame is arranged between the first polarizing plate and the liquid crystal panel.
4. The cover panel according to claim 1 , wherein the light-shielding frame is arranged between the louver layer and the first polarizing plate.
5. The cover panel according to claim 1 , wherein a first cross-sectional area of the light absorbing members parallel to a front surface of the first reflection suppressing film is smaller than a second cross-sectional area of the light absorbing members parallel to the front surface of the first reflection suppressing film and at a position closer to the first polarizing plate.
6. The cover panel according to claim 1 , wherein a first cross-sectional area of the light absorbing members parallel to a front surface of the first reflection suppressing film is larger than a second cross-sectional area of the light absorbing members parallel to the front surface of the first reflection suppressing film and at a position closer to the first polarizing plate.
7. The cover panel according to claim 2 , further comprising a touch panel arranged between the first polarizing plate and the liquid crystal panel, wherein
the light-shielding frame is arranged between the first polarizing plate and the touch panel.
8. The cover panel according to claim 1 , wherein
the first polarizing plate includes a first surface facing the first reflection suppressing film and a second surface opposite to the first surface, and
the cover panel further comprises a second reflection suppressing film that is arranged to be opposed to the second surface and suppresses reflection of light at the second surface.
9. The cover panel according to claim 8 , wherein the second reflection suppressing film is bonded to the second surface by an adhesive layer containing a material for adjusting transmittance of light.
10. The cover panel according to claim 1 , wherein the cover panel has a curved surface.
11. The cover panel according to claim 1 , wherein the cover panel comprises a decorative layer between the first reflection suppressing film and the first polarizing plate, and comprises the louver layer between the decorative layer and the first polarizing plate.
12. The cover panel according to claim 11 , further comprising a light-shielding frame that is arranged between the louver layer and the liquid crystal panel, and overlaps a peripheral portion of the first polarizing plate when transparently viewed from a direction perpendicular to a front surface of the first reflection suppressing film.
13. The cover panel according to claim 11 , further including a touch panel arranged between the first polarizing plate and the liquid crystal panel.
14. The cover panel according to claim 13 , further comprising a light-shielding frame that is arranged between the first polarizing plate and the touch panel, and overlaps a peripheral portion of the first polarizing plate when transparently viewed from a direction perpendicular to a front surface of the first reflection suppressing film.
15. A display device comprising:
the liquid crystal panel; and
the cover panel according to claim 1 that is arranged to be opposed to a front surface of the liquid crystal panel and to be spaced apart from the liquid crystal panel by the air layer, wherein
the liquid crystal panel includes:
a liquid crystal layer; and
a second polarizing plate that is arranged to be opposed to a rear surface of the liquid crystal layer, and polarizes light.
16. The display device according to claim 15 , wherein no polarizing plate is arranged between the first polarizing plate and the liquid crystal layer.
