Topic: 6 Session: oral Abstract: Based on a large sample Seyfert 2 galaxies with both optical spectropolarimetric and X-ray data, we show that in additional to the nuclei activity, the obscuration also play an important role in the visibility of polarized broad emission lines in Sy2s. We can reach the results in the unified model if: a) the absorption column density is higher at large inclinations and b) the scattering region is obscured at large inclinations.
