Rate is crossed also less than 8%, illustrates that the second light that the wavelength more than 92% is 550nm is absorbed, at this time, metal wire is reflective to display
The influence of the contrast of device is smaller, disclosure satisfy that the requirement of contrast；And the of the quarter wave plate with other phase differences
The transmitance to the second light that wavelength is 550nm of one structure of polarized light is lower, has more to the second light that wavelength is 550nm
Good assimilation effect.When the position phase difference of the quarter wave plate of the first structure of polarized light is 137.5nm, the first structure of polarized light is to wavelength
For 550nm the second light transmitance close to 0, illustrate the second light that nearly all wavelength is 550nm all by the first polarisation
Structure absorbs, and the contrast of display device is optimal.
