>>just patenting an anti-reflective film<<

Column 1, line 67 through column 2, line 41 explains the gist of the problem.

... For large area displays, the counter electrode must have a low electrical resistivity, and hence, this usually requires it be made out of a metal such as aluminum. Unfortunately, this results in a device having a large reflectance in the visible portion of the optical spectrum.

{less reflective electrode materials may have since become available}

Their solution is to sandwich an interference film above and in contact with the front face of the counter electrode.
