Wire grid polarizer device and manufacturing method, a display device

The present invention provides a kind of wire-grid polarizer device and manufacturing method thereof, a display apparatus, the wire grid polarizer device comprises a substrate and a substrate and a metal wire grid nanotube wire grid on the base substrate, the metal wire grid the carbon nanotube wire-grid and stacked, the nanotube comprises carbon nanotube wire grid of the same plurality of axial directions. Wire-grid polarizer of the present invention provides a device including stacked carbon nanotube and a metal wire grid of the wire grid, in the production of the wire-grid polarizer device, thickness of the metal to avoid high plasma dry etching process, thereby reducing the difficulty of the production process enhanced process stability and chemical stability of the wire grid polarizer.
